CPack: Move internal implementation modules into Internal/CPack directory

These modules are not meant to be included by user code, they are
only an internal implementation detail for CPack. Having them live
in the main Modules directory with documentation was misleading, so
they have been moved into Modules/Internal/CPack, and their
documentation has been stripped following its move into the new
"CPack Generators" section. No-op modules which contained only
documentation have been removed entirely.

The only module that hasn't been moved is CPackIFW, because it
contains user-facing macros which would be lost if it were moved.
So, the CPackIFW module has been updated with a note explaining what
needs to (eventually) happen.

-#
-# Variables specific to CPack Bundle generator
-# ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-#
-# Installers built on Mac OS X using the Bundle generator use the
-# aforementioned DragNDrop (CPACK_DMG_xxx) variables, plus the following
-# Bundle-specific parameters (CPACK_BUNDLE_xxx).
-#
-# .. variable:: CPACK_BUNDLE_NAME
-#
-#  The name of the generated bundle. This appears in the OSX finder as the
-#  bundle name. Required.
-#
-# .. variable:: CPACK_BUNDLE_PLIST
-#
-#  Path to an OSX plist file that will be used for the generated bundle. This
-#  assumes that the caller has generated or specified their own Info.plist
-#  file. Required.
-#
-# .. variable:: CPACK_BUNDLE_ICON
-#
-#  Path to an OSX icon file that will be used as the icon for the generated
-#  bundle. This is the icon that appears in the OSX finder for the bundle, and
-#  in the OSX dock when the bundle is opened.  Required.
-#
-# .. variable:: CPACK_BUNDLE_STARTUP_COMMAND
-#
-#  Path to a startup script. This is a path to an executable or script that
-#  will be run whenever an end-user double-clicks the generated bundle in the
-#  OSX Finder. Optional.
-#
-# .. variable:: CPACK_BUNDLE_APPLE_CERT_APP
-#
-#  The name of your Apple supplied code signing certificate for the application.
-#  The name usually takes the form "Developer ID Application: [Name]" or
-#  "3rd Party Mac Developer Application: [Name]". If this variable is not set
-#  the application will not be signed.
-#
-# .. variable:: CPACK_BUNDLE_APPLE_ENTITLEMENTS
-#
-#  The name of the plist file that contains your apple entitlements for sandboxing
-#  your application. This file is required for submission to the Mac App Store.
-#
-# .. variable:: CPACK_BUNDLE_APPLE_CODESIGN_FILES
-#
-#  A list of additional files that you wish to be signed. You do not need to
-#  list the main application folder, or the main executable. You should
-#  list any frameworks and plugins that are included in your app bundle.
-#
-# .. variable:: CPACK_BUNDLE_APPLE_CODESIGN_PARAMETER
-#
-#  Additional parameter that will passed to codesign.
-#  Default value: "--deep -f"
-#
-# .. variable:: CPACK_COMMAND_CODESIGN
-#
-#  Path to the codesign(1) command used to sign applications with an
-#  Apple cert. This variable can be used to override the automatically
-#  detected command (or specify its location if the auto-detection fails
-#  to find it.)

-# DragNDrop CPack generator (Mac OS X).
-#
-# Variables specific to CPack DragNDrop generator
-# ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-#
-# The following variables are specific to the DragNDrop installers built
-# on Mac OS X:
-#
-# .. variable:: CPACK_DMG_VOLUME_NAME
-#
-#  The volume name of the generated disk image. Defaults to
-#  CPACK_PACKAGE_FILE_NAME.
-#
-# .. variable:: CPACK_DMG_FORMAT
-#
-#  The disk image format. Common values are UDRO (UDIF read-only), UDZO (UDIF
-#  zlib-compressed) or UDBZ (UDIF bzip2-compressed). Refer to hdiutil(1) for
-#  more information on other available formats. Defaults to UDZO.
-#
-# .. variable:: CPACK_DMG_DS_STORE
-#
-#  Path to a custom DS_Store file. This .DS_Store file e.g. can be used to
-#  specify the Finder window position/geometry and layout (such as hidden
-#  toolbars, placement of the icons etc.). This file has to be generated by
-#  the Finder (either manually or through AppleScript) using a normal folder
-#  from which the .DS_Store file can then be extracted.
-#
-# .. variable:: CPACK_DMG_DS_STORE_SETUP_SCRIPT
-#
-#  Path to a custom AppleScript file.  This AppleScript is used to generate
-#  a .DS_Store file which specifies the Finder window position/geometry and
-#  layout (such as hidden toolbars, placement of the icons etc.).
-#  By specifying a custom AppleScript there is no need to use
-#  CPACK_DMG_DS_STORE, as the .DS_Store that is generated by the AppleScript
-#  will be packaged.
-#
-# .. variable:: CPACK_DMG_BACKGROUND_IMAGE
-#
-#  Path to an image file to be used as the background.  This file will be
-#  copied to .background/background.<ext>, where ext is the original image file
-#  extension.  The background image is installed into the image before
-#  CPACK_DMG_DS_STORE_SETUP_SCRIPT is executed or CPACK_DMG_DS_STORE is
-#  installed.  By default no background image is set.
-#
-# .. variable:: CPACK_DMG_DISABLE_APPLICATIONS_SYMLINK
-#
-#  Default behaviour is to include a symlink to ``/Applications`` in the DMG.
-#  Set this option to ``ON`` to avoid adding the symlink.
-#
-# .. variable:: CPACK_DMG_SLA_DIR
-#
-#   Directory where license and menu files for different languages are stored.
-#   Setting this causes CPack to look for a ``<language>.menu.txt`` and
-#   ``<language>.license.txt`` file for every language defined in
-#   ``CPACK_DMG_SLA_LANGUAGES``. If both this variable and
-#   ``CPACK_RESOURCE_FILE_LICENSE`` are set, CPack will only look for the menu
-#   files and use the same license file for all languages.
-#
-# .. variable:: CPACK_DMG_SLA_LANGUAGES
-#
-#   Languages for which a license agreement is provided when mounting the
-#   generated DMG. A menu file consists of 9 lines of text. The first line is
-#   is the name of the language itself, uppercase, in English (e.g. German).
-#   The other lines are translations of the following strings:
-#
-#   - Agree
-#   - Disagree
-#   - Print
-#   - Save...
-#   - You agree to the terms of the License Agreement when you click the
-#     "Agree" button.
-#   - Software License Agreement
-#   - This text cannot be saved. The disk may be full or locked, or the file
-#     may be locked.
-#   - Unable to print. Make sure you have selected a printer.
-#
-#   For every language in this list, CPack will try to find files
-#   ``<language>.menu.txt`` and ``<language>.license.txt`` in the directory
-#   specified by the :variable:`CPACK_DMG_SLA_DIR` variable.
-#
-# .. variable:: CPACK_COMMAND_HDIUTIL
-#
-#  Path to the hdiutil(1) command used to operate on disk image files on Mac
-#  OS X. This variable can be used to override the automatically detected
-#  command (or specify its location if the auto-detection fails to find it.)
-#
-# .. variable:: CPACK_COMMAND_SETFILE
-#
-#  Path to the SetFile(1) command used to set extended attributes on files and
-#  directories on Mac OS X. This variable can be used to override the
-#  automatically detected command (or specify its location if the
-#  auto-detection fails to find it.)
-#
-# .. variable:: CPACK_COMMAND_REZ

-CPackFreeBSD
-------------
-
-The built in (binary) CPack FreeBSD (pkg) generator (Unix only)
-
-Variables specific to CPack FreeBSD (pkg) generator
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-CPackFreeBSD may be used to create pkg(8) packages -- these may be used
-on FreeBSD, DragonflyBSD, NetBSD, OpenBSD, but also on Linux or OSX,
-depending on the installed package-management tools -- using :module:`CPack`.
-
-CPackFreeBSD is a :module:`CPack` generator and uses the ``CPACK_XXX``
-variables used by :module:`CPack`. It tries to re-use packaging information
-that may already be specified for Debian packages for the :module:`CPackDeb`
-generator. it also tries to re-use RPM packaging information when Debian
-does not specify.
-
-CPackFreeBSD generator should work on any host with libpkg installed. The
-packages it produces are specific to the host architecture and ABI.
-
-CPackFreeBSD sets package-metadata through :code:`CPACK_FREEBSD_XXX` variables.
-CPackFreeBSD, unlike CPackDeb, does not specially support componentized
-packages; a single package is created from all the software artifacts
-created through CMake.
-
-All of the variables can be set specifically for FreeBSD packaging in
-the CPackConfig file or in CMakeLists.txt, but most of them have defaults
-that use general settings (e.g. CMAKE_PROJECT_NAME) or Debian-specific
-variables when those make sense (e.g. the homepage of an upstream project
-is usually unchanged by the flavor of packaging). When there is no Debian
-information to fall back on, but the RPM packaging has it, fall back to
-the RPM information (e.g. package license).
-
-.. variable:: CPACK_FREEBSD_PACKAGE_NAME
-
-  Sets the package name (in the package manifest, but also affects the
-  output filename).
-
-  * Mandatory: YES
-  * Default:
-
-    - :variable:`CPACK_PACKAGE_NAME` (this is always set by CPack itself,
-      based on CMAKE_PROJECT_NAME).
-
-.. variable:: CPACK_FREEBSD_PACKAGE_COMMENT
-
-  Sets the package comment. This is the short description displayed by
-  pkg(8) in standard "pkg info" output.
-
-  * Mandatory: YES
-  * Default:
-
-    - :variable:`CPACK_PACKAGE_DESCRIPTION_SUMMARY` (this is always set
-      by CPack itself, if nothing else sets it explicitly).
-    - :variable:`PROJECT_DESCRIPTION` (this can be set with the DESCRIPTION
-      parameter for :command:`project`).
-
-.. variable:: CPACK_FREEBSD_PACKAGE_DESCRIPTION
-
-  Sets the package description. This is the long description of the package,
-  given by "pkg info" with a specific package as argument.
-
-  * Mandatory: YES
-  * Default:
-
-    - :variable:`CPACK_DEBIAN_PACKAGE_DESCRIPTION` (this may be set already
-      for Debian packaging, so we may as well re-use it).
-
-.. variable:: CPACK_FREEBSD_PACKAGE_WWW
-
-  The URL of the web site for this package, preferably (when applicable) the
-  site from which the original source can be obtained and any additional
-  upstream documentation or information may be found.
-
-  * Mandatory: YES
-  * Default:
-
-   - :variable:`CMAKE_PROJECT_HOMEPAGE_URL`, or if that is not set,
-     :variable:`CPACK_DEBIAN_PACKAGE_HOMEPAGE` (this may be set already
-     for Debian packaging, so we may as well re-use it).
-
-.. variable:: CPACK_FREEBSD_PACKAGE_LICENSE
-
-  The license, or licenses, which apply to this software package. This must
-  be one or more license-identifiers that pkg recognizes as acceptable license
-  identifiers (e.g. "GPLv2").
-
-  * Mandatory: YES
-  * Default:
-
-    - :variable:`CPACK_RPM_PACKAGE_LICENSE`
-
-.. variable:: CPACK_FREEBSD_PACKAGE_LICENSE_LOGIC
-
-  This variable is only of importance if there is more than one license.
-  The default is "single", which is only applicable to a single license.
-  Other acceptable values are determined by pkg -- those are "dual" or "multi" --
-  meaning choice (OR) or simultaneous (AND) application of the licenses.
-
-  * Mandatory: NO
-  * Default: single
-
-.. variable:: CPACK_FREEBSD_PACKAGE_MAINTAINER
-
-  The FreeBSD maintainer (e.g. kde@freebsd.org) of this package.
-
-  * Mandatory: YES
-  * Default: none
-
-.. variable:: CPACK_FREEBSD_PACKAGE_ORIGIN
-
-  The origin (ports label) of this package; for packages built by CPack
-  outside of the ports system this is of less importance. The default
-  puts the package somewhere under misc/, as a stopgap.
-
-  * Mandatory: YES
-  * Default: misc/<package name>
-
-.. variable:: CPACK_FREEBSD_PACKAGE_CATEGORIES
-
-  The ports categories where this package lives (if it were to be built
-  from ports). If none is set a single category is determined based on
-  the package origin.
-
-  * Mandatory: YES
-  * Default: derived from ORIGIN
-
-.. variable:: CPACK_FREEBSD_PACKAGE_DEPS
-
-  A list of package origins that should be added as package dependencies.
-  These are in the form <category>/<packagename>, e.g. x11/libkonq.
-  No version information needs to be provided (this is not included
-  in the manifest).
-
-  * Mandatory: NO
-  * Default: empty

-#  Additional NSIS commands to uninstall start menu shortcuts.
-#
-# .. variable:: CPACK_NSIS_EXECUTABLES_DIRECTORY
-#
-#  Creating NSIS start menu links assumes that they are in 'bin' unless this

-#  executables are in an exec directory.
-#
-# .. variable:: CPACK_NSIS_MUI_FINISHPAGE_RUN
-#
-#  Specify an executable to add an option to run on the finish page of the

-# CPackWIX
-# --------
-#
-# CPack WiX generator specific options
-#
-# Variables specific to CPack WiX generator
-# ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-#
-# The following variables are specific to the installers built on
-# Windows using WiX.
-#
-# .. variable:: CPACK_WIX_UPGRADE_GUID
-#
-#  Upgrade GUID (``Product/@UpgradeCode``)
-#
-#  Will be automatically generated unless explicitly provided.
-#
-#  It should be explicitly set to a constant generated globally unique
-#  identifier (GUID) to allow your installers to replace existing
-#  installations that use the same GUID.
-#
-#  You may for example explicitly set this variable in your
-#  CMakeLists.txt to the value that has been generated per default.  You
-#  should not use GUIDs that you did not generate yourself or which may
-#  belong to other projects.
-#
-#  A GUID shall have the following fixed length syntax::
-#
-#   XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX
-#
-#  (each X represents an uppercase hexadecimal digit)
-#
-# .. variable:: CPACK_WIX_PRODUCT_GUID
-#
-#  Product GUID (``Product/@Id``)
-#
-#  Will be automatically generated unless explicitly provided.
-#
-#  If explicitly provided this will set the Product Id of your installer.
-#
-#  The installer will abort if it detects a pre-existing installation that
-#  uses the same GUID.
-#
-#  The GUID shall use the syntax described for CPACK_WIX_UPGRADE_GUID.
-#
-# .. variable:: CPACK_WIX_LICENSE_RTF
-#
-#  RTF License File
-#
-#  If CPACK_RESOURCE_FILE_LICENSE has an .rtf extension it is used as-is.
-#
-#  If CPACK_RESOURCE_FILE_LICENSE has an .txt extension it is implicitly
-#  converted to RTF by the WiX Generator.
-#  The expected encoding of the .txt file is UTF-8.
-#
-#  With CPACK_WIX_LICENSE_RTF you can override the license file used by the
-#  WiX Generator in case CPACK_RESOURCE_FILE_LICENSE is in an unsupported
-#  format or the .txt -> .rtf conversion does not work as expected.
-#
-# .. variable:: CPACK_WIX_PRODUCT_ICON
-#
-#  The Icon shown next to the program name in Add/Remove programs.
-#
-#  If set, this icon is used in place of the default icon.
-#
-# .. variable:: CPACK_WIX_UI_REF
-#
-#  This variable allows you to override the Id of the ``<UIRef>`` element
-#  in the WiX template.
-#
-#  The default is ``WixUI_InstallDir`` in case no CPack components have
-#  been defined and ``WixUI_FeatureTree`` otherwise.
-#
-# .. variable:: CPACK_WIX_UI_BANNER
-#
-#  The bitmap will appear at the top of all installer pages other than the
-#  welcome and completion dialogs.
-#
-#  If set, this image will replace the default banner image.
-#
-#  This image must be 493 by 58 pixels.
-#
-# .. variable:: CPACK_WIX_UI_DIALOG
-#
-#  Background bitmap used on the welcome and completion dialogs.
-#
-#  If this variable is set, the installer will replace the default dialog
-#  image.
-#
-#  This image must be 493 by 312 pixels.
-#
-# .. variable:: CPACK_WIX_PROGRAM_MENU_FOLDER
-#
-#  Start menu folder name for launcher.
-#
-#  If this variable is not set, it will be initialized with CPACK_PACKAGE_NAME
-#
-# .. variable:: CPACK_WIX_CULTURES
-#
-#  Language(s) of the installer
-#
-#  Languages are compiled into the WixUI extension library.  To use them,
-#  simply provide the name of the culture.  If you specify more than one
-#  culture identifier in a comma or semicolon delimited list, the first one
-#  that is found will be used.  You can find a list of supported languages at:
-#  http://wix.sourceforge.net/manual-wix3/WixUI_localization.htm
-#
-# .. variable:: CPACK_WIX_TEMPLATE
-#
-#  Template file for WiX generation
-#
-#  If this variable is set, the specified template will be used to generate
-#  the WiX wxs file.  This should be used if further customization of the
-#  output is required.
-#
-#  If this variable is not set, the default MSI template included with CMake
-#  will be used.
-#
-# .. variable:: CPACK_WIX_PATCH_FILE
-#
-#  Optional list of XML files with fragments to be inserted into
-#  generated WiX sources
-#
-#  This optional variable can be used to specify an XML file that the
-#  WiX generator will use to inject fragments into its generated
-#  source files.
-#
-#  Patch files understood by the CPack WiX generator
-#  roughly follow this RELAX NG compact schema:
-#
-#  .. code-block:: none
-#
-#     start = CPackWiXPatch
-#
-#     CPackWiXPatch = element CPackWiXPatch { CPackWiXFragment* }
-#
-#     CPackWiXFragment = element CPackWiXFragment
-#     {
-#         attribute Id { string },
-#         fragmentContent*
-#     }
-#
-#     fragmentContent = element * - CPackWiXFragment
-#     {
-#         (attribute * { text } | text | fragmentContent)*
-#     }
-#
-#  Currently fragments can be injected into most
-#  Component, File, Directory and Feature elements.
-#
-#  The following additional special Ids can be used:
-#
-#  * ``#PRODUCT`` for the ``<Product>`` element.
-#  * ``#PRODUCTFEATURE`` for the root ``<Feature>`` element.
-#
-#  The following example illustrates how this works.
-#
-#  Given that the WiX generator creates the following XML element:
-#
-#  .. code-block:: xml
-#
-#     <Component Id="CM_CP_applications.bin.my_libapp.exe" Guid="*"/>
-#
-#  The following XML patch file may be used to inject an Environment element
-#  into it:
-#
-#  .. code-block:: xml
-#
-#     <CPackWiXPatch>
-#       <CPackWiXFragment Id="CM_CP_applications.bin.my_libapp.exe">
-#         <Environment Id="MyEnvironment" Action="set"
-#           Name="MyVariableName" Value="MyVariableValue"/>
-#       </CPackWiXFragment>
-#     </CPackWiXPatch>
-#
-# .. variable:: CPACK_WIX_EXTRA_SOURCES
-#
-#  Extra WiX source files
-#
-#  This variable provides an optional list of extra WiX source files (.wxs)
-#  that should be compiled and linked.  The full path to source files is
-#  required.
-#
-# .. variable:: CPACK_WIX_EXTRA_OBJECTS
-#
-#  Extra WiX object files or libraries
-#
-#  This variable provides an optional list of extra WiX object (.wixobj)
-#  and/or WiX library (.wixlib) files.  The full path to objects and libraries
-#  is required.
-#
-# .. variable:: CPACK_WIX_EXTENSIONS
-#
-#  This variable provides a list of additional extensions for the WiX
-#  tools light and candle.
-#
-# .. variable:: CPACK_WIX_<TOOL>_EXTENSIONS
-#
-#  This is the tool specific version of CPACK_WIX_EXTENSIONS.
-#  ``<TOOL>`` can be either LIGHT or CANDLE.
-#
-# .. variable:: CPACK_WIX_<TOOL>_EXTRA_FLAGS
-#
-#  This list variable allows you to pass additional
-#  flags to the WiX tool ``<TOOL>``.
-#
-#  Use it at your own risk.
-#  Future versions of CPack may generate flags which may be in conflict
-#  with your own flags.
-#
-#  ``<TOOL>`` can be either LIGHT or CANDLE.
-#
-# .. variable:: CPACK_WIX_CMAKE_PACKAGE_REGISTRY
-#
-#  If this variable is set the generated installer will create
-#  an entry in the windows registry key
-#  ``HKEY_LOCAL_MACHINE\Software\Kitware\CMake\Packages\<package>``
-#  The value for ``<package>`` is provided by this variable.
-#
-#  Assuming you also install a CMake configuration file this will
-#  allow other CMake projects to find your package with
-#  the :command:`find_package` command.
-#
-# .. variable:: CPACK_WIX_PROPERTY_<PROPERTY>
-#
-#  This variable can be used to provide a value for
-#  the Windows Installer property ``<PROPERTY>``
-#
-#  The following list contains some example properties that can be used to
-#  customize information under
-#  "Programs and Features" (also known as "Add or Remove Programs")
-#
-#  * ARPCOMMENTS - Comments
-#  * ARPHELPLINK - Help and support information URL
-#  * ARPURLINFOABOUT - General information URL
-#  * ARPURLUPDATEINFO - Update information URL
-#  * ARPHELPTELEPHONE - Help and support telephone number
-#  * ARPSIZE - Size (in kilobytes) of the application
-#
-# .. variable:: CPACK_WIX_ROOT_FEATURE_TITLE
-#
-#  Sets the name of the root install feature in the WIX installer. Same as
-#  CPACK_COMPONENT_<compName>_DISPLAY_NAME for components.
-#
-# .. variable:: CPACK_WIX_ROOT_FEATURE_DESCRIPTION
-#
-#  Sets the description of the root install feature in the WIX installer. Same as
-#  CPACK_COMPONENT_<compName>_DESCRIPTION for components.
-#
-# .. variable:: CPACK_WIX_SKIP_PROGRAM_FOLDER
-#
-#  If this variable is set to true, the default install location
-#  of the generated package will be CPACK_PACKAGE_INSTALL_DIRECTORY directly.
-#  The install location will not be located relatively below
-#  ProgramFiles or ProgramFiles64.
-#
-#   .. note::
-#     Installers created with this feature do not take differences
-#     between the system on which the installer is created
-#     and the system on which the installer might be used into account.
-#
-#     It is therefore possible that the installer e.g. might try to install
-#     onto a drive that is unavailable or unintended or a path that does not
-#     follow the localization or convention of the system on which the
-#     installation is performed.
-#
-# .. variable:: CPACK_WIX_ROOT_FOLDER_ID
-#
-#  This variable allows specification of a custom root folder ID.
-#  The generator specific ``<64>`` token can be used for
-#  folder IDs that come in 32-bit and 64-bit variants.
-#  In 32-bit builds the token will expand empty while in 64-bit builds
-#  it will expand to ``64``.
-#
-#  When unset generated installers will default installing to
-#  ``ProgramFiles<64>Folder``.
-#
-# .. variable:: CPACK_WIX_ROOT
-#
-#  This variable can optionally be set to the root directory
-#  of a custom WiX Toolset installation.
-#
-#  When unspecified CPack will try to locate a WiX Toolset
-#  installation via the ``WIX`` environment variable instead.
-#

-# CPackDeb
-# --------
-#
-# The built in (binary) CPack Deb generator (Unix only)
-#
-# Variables specific to CPack Debian (DEB) generator
-# ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-#
-# CPackDeb may be used to create Deb package using :module:`CPack`.
-# CPackDeb is a :module:`CPack` generator thus it uses the ``CPACK_XXX``
-# variables used by :module:`CPack`.
-#
-# CPackDeb generator should work on any Linux host but it will produce
-# better deb package when Debian specific tools ``dpkg-xxx`` are usable on
-# the build system.
-#
-# CPackDeb has specific features which are controlled by the specifics
-# :code:`CPACK_DEBIAN_XXX` variables.
-#
-# :code:`CPACK_DEBIAN_<COMPONENT>_XXXX` variables may be used in order to have
-# **component** specific values.  Note however that ``<COMPONENT>`` refers to
-# the **grouping name** written in upper case. It may be either a component name
-# or a component GROUP name.
-#
-# Here are some CPackDeb wiki resources that are here for historic reasons and
-# are no longer maintained but may still prove useful:
-#
-#  - https://gitlab.kitware.com/cmake/community/wikis/doc/cpack/Configuration
-#  - https://gitlab.kitware.com/cmake/community/wikis/doc/cpack/PackageGenerators#deb-unix-only
-#
-# List of CPackDEB specific variables:
-#
-# .. variable:: CPACK_DEB_COMPONENT_INSTALL
-#
-#  Enable component packaging for CPackDEB
-#
-#  * Mandatory : NO
-#  * Default   : OFF
-#
-#  If enabled (ON) multiple packages are generated. By default a single package
-#  containing files of all components is generated.
-#
-# .. variable:: CPACK_DEBIAN_PACKAGE_NAME
-#               CPACK_DEBIAN_<COMPONENT>_PACKAGE_NAME
-#
-#  Set Package control field (variable is automatically transformed to lower
-#  case).
-#
-#  * Mandatory : YES
-#  * Default   :
-#
-#    - :variable:`CPACK_PACKAGE_NAME` for non-component based
-#      installations
-#    - :variable:`CPACK_DEBIAN_PACKAGE_NAME` suffixed with -<COMPONENT>
-#      for component-based installations.
-#
-#  See https://www.debian.org/doc/debian-policy/ch-controlfields.html#s-f-Source
-#
-# .. variable:: CPACK_DEBIAN_FILE_NAME
-#               CPACK_DEBIAN_<COMPONENT>_FILE_NAME
-#
-#  Package file name.
-#
-#  * Mandatory : YES
-#  * Default   : ``<CPACK_PACKAGE_FILE_NAME>[-<component>].deb``
-#
-#  This may be set to ``DEB-DEFAULT`` to allow CPackDeb to generate package file
-#  name by itself in deb format::
-#
-#    <PackageName>_<VersionNumber>-<DebianRevisionNumber>_<DebianArchitecture>.deb
-#
-#  Alternatively provided package file name must end
-#  with either ``.deb`` or ``.ipk`` suffix.
-#
-#  .. note::
-#
-#    Preferred setting of this variable is ``DEB-DEFAULT`` but for backward
-#    compatibility with CPackDeb in CMake prior to version 3.6 this feature
-#    is disabled by default.
-#
-#  .. note::
-#
-#    By using non default filenames duplicate names may occur. Duplicate files
-#    get overwritten and it is up to the packager to set the variables in a
-#    manner that will prevent such errors.
-#
-# .. variable:: CPACK_DEBIAN_PACKAGE_EPOCH
-#
-#  The Debian package epoch
-#
-#  * Mandatory : No
-#  * Default   : -
-#
-#  Optional number that should be incremented when changing versioning schemas
-#  or fixing mistakes in the version numbers of older packages.
-#
-# .. variable:: CPACK_DEBIAN_PACKAGE_VERSION
-#
-#  The Debian package version
-#
-#  * Mandatory : YES
-#  * Default   : :variable:`CPACK_PACKAGE_VERSION`
-#
-#  This variable may contain only alphanumerics (A-Za-z0-9) and the characters
-#  . + - ~ (full stop, plus, hyphen, tilde) and should start with a digit. If
-#  :variable:`CPACK_DEBIAN_PACKAGE_RELEASE` is not set then hyphens are not
-#  allowed.
-#
-#  .. note::
-#
-#    For backward compatibility with CMake 3.9 and lower a failed test of this
-#    variable's content is not a hard error when both
-#    :variable:`CPACK_DEBIAN_PACKAGE_RELEASE` and
-#    :variable:`CPACK_DEBIAN_PACKAGE_EPOCH` variables are not set. An author
-#    warning is reported instead.
-#
-# .. variable:: CPACK_DEBIAN_PACKAGE_RELEASE
-#
-#  The Debian package release - Debian revision number.
-#
-#  * Mandatory : No
-#  * Default   : -
-#
-#  This is the numbering of the DEB package itself, i.e. the version of the
-#  packaging and not the version of the content (see
-#  :variable:`CPACK_DEBIAN_PACKAGE_VERSION`). One may change the default value
-#  if the previous packaging was buggy and/or you want to put here a fancy Linux
-#  distro specific numbering.
-#
-# .. variable:: CPACK_DEBIAN_PACKAGE_ARCHITECTURE
-#               CPACK_DEBIAN_<COMPONENT>_PACKAGE_ARCHITECTURE
-#
-#  The Debian package architecture
-#
-#  * Mandatory : YES
-#  * Default   : Output of :code:`dpkg --print-architecture` (or :code:`i386`
-#    if :code:`dpkg` is not found)
-#
-# .. variable:: CPACK_DEBIAN_PACKAGE_DEPENDS
-#               CPACK_DEBIAN_<COMPONENT>_PACKAGE_DEPENDS
-#
-#  Sets the Debian dependencies of this package.
-#
-#  * Mandatory : NO
-#  * Default   :
-#
-#    - An empty string for non-component based installations
-#    - :variable:`CPACK_DEBIAN_PACKAGE_DEPENDS` for component-based
-#      installations.
-#
-#  .. note::
-#
-#    If :variable:`CPACK_DEBIAN_PACKAGE_SHLIBDEPS` or
-#    more specifically :variable:`CPACK_DEBIAN_<COMPONENT>_PACKAGE_SHLIBDEPS`
-#    is set for this component, the discovered dependencies will be appended
-#    to :variable:`CPACK_DEBIAN_<COMPONENT>_PACKAGE_DEPENDS` instead of
-#    :variable:`CPACK_DEBIAN_PACKAGE_DEPENDS`. If
-#    :variable:`CPACK_DEBIAN_<COMPONENT>_PACKAGE_DEPENDS` is an empty string,
-#    only the automatically discovered dependencies will be set for this
-#    component.
-#
-#  Example::
-#
-#    set(CPACK_DEBIAN_PACKAGE_DEPENDS "libc6 (>= 2.3.1-6), libc6 (< 2.4)")
-#
-# .. variable:: CPACK_DEBIAN_ENABLE_COMPONENT_DEPENDS
-#
-#  Sets inter component dependencies if listed with
-#  :variable:`CPACK_COMPONENT_<compName>_DEPENDS` variables.
-#
-#  * Mandatory : NO
-#  * Default   : -
-#
-# .. variable:: CPACK_DEBIAN_PACKAGE_MAINTAINER
-#
-#  The Debian package maintainer
-#
-#  * Mandatory : YES
-#  * Default   : :code:`CPACK_PACKAGE_CONTACT`
-#

-CPackNuGet
-----------
-
-When build a NuGet package there is no direct way to control an output
-filename due a lack of the corresponding CLI option of NuGet, so there
-is no ``CPACK_NUGET_PACKAGE_FILENAME`` variable. To form the output filename
-NuGet uses the package name and the version according to its built-in rules.
-
-Also, be aware that including a top level directory
-(``CPACK_INCLUDE_TOPLEVEL_DIRECTORY``) is ignored by this generator.
-
-
-Variables specific to CPack NuGet generator
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-CPackNuGet may be used to create NuGet packages using :module:`CPack`.
-CPackNuGet is a :module:`CPack` generator thus it uses the ``CPACK_XXX``
-variables used by :module:`CPack`.
-
-CPackNuGet has specific features which are controlled by the specifics
-:code:`CPACK_NUGET_XXX` variables. In the "one per group" mode
-(see :variable:`CPACK_COMPONENTS_GROUPING`), ``<compName>`` placeholder
-in the variables below would contain a group name (uppercased and turned into
-a "C" identifier).
-
-List of CPackNuGet specific variables:

-# CPackRPM
-# --------
-#
-# The built in (binary) CPack RPM generator (Unix only)
-#
-# Variables specific to CPack RPM generator
-# ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-#
-# CPackRPM may be used to create RPM packages using :module:`CPack`.
-# CPackRPM is a :module:`CPack` generator thus it uses the ``CPACK_XXX``
-# variables used by :module:`CPack`.
-#
-# CPackRPM has specific features which are controlled by the specifics
-# :code:`CPACK_RPM_XXX` variables.
-#
-# :code:`CPACK_RPM_<COMPONENT>_XXXX` variables may be used in order to have
-# **component** specific values.  Note however that ``<COMPONENT>`` refers to the
-# **grouping name** written in upper case. It may be either a component name or
-# a component GROUP name. Usually those variables correspond to RPM spec file
-# entities. One may find information about spec files here
-# http://www.rpm.org/wiki/Docs
-#
-# .. note::
-#
-#  `<COMPONENT>` part of variables is preferred to be in upper case (for e.g. if
-#  component is named `foo` then use `CPACK_RPM_FOO_XXXX` variable name format)
-#  as is with other `CPACK_<COMPONENT>_XXXX` variables.
-#  For the purposes of back compatibility (CMake/CPack version 3.5 and lower)
-#  support for same cased component (e.g. `fOo` would be used as
-#  `CPACK_RPM_fOo_XXXX`) is still supported for variables defined in older
-#  versions of CMake/CPack but is not guaranteed for variables that
-#  will be added in the future. For the sake of back compatibility same cased
-#  component variables also override upper cased versions where both are
-#  present.
-#
-# Here are some CPackRPM wiki resources that are here for historic reasons and
-# are no longer maintained but may still prove useful:
-#
-#  - https://gitlab.kitware.com/cmake/community/wikis/doc/cpack/Configuration
-#  - https://gitlab.kitware.com/cmake/community/wikis/doc/cpack/PackageGenerators#rpm-unix-only
-#
-# List of CPackRPM specific variables:
-#
-# .. variable:: CPACK_RPM_COMPONENT_INSTALL
-#
-#  Enable component packaging for CPackRPM
-#
-#  * Mandatory : NO
-#  * Default   : OFF
-#
-#  If enabled (ON) multiple packages are generated. By default a single package
-#  containing files of all components is generated.
-#
-# .. variable:: CPACK_RPM_PACKAGE_SUMMARY
-#               CPACK_RPM_<component>_PACKAGE_SUMMARY
-#
-#  The RPM package summary.
-#
-#  * Mandatory : YES
-#  * Default   : :variable:`CPACK_PACKAGE_DESCRIPTION_SUMMARY`
-#
-# .. variable:: CPACK_RPM_PACKAGE_NAME
-#               CPACK_RPM_<component>_PACKAGE_NAME
-#
-#  The RPM package name.
-#
-#  * Mandatory : YES
-#  * Default   : :variable:`CPACK_PACKAGE_NAME`
-#
-# .. variable:: CPACK_RPM_FILE_NAME
-#               CPACK_RPM_<component>_FILE_NAME
-#
-#  Package file name.
-#
-#  * Mandatory : YES
-#  * Default   : ``<CPACK_PACKAGE_FILE_NAME>[-<component>].rpm`` with spaces
-#                replaced by '-'
-#
-#  This may be set to ``RPM-DEFAULT`` to allow rpmbuild tool to generate package
-#  file name by itself.
-#  Alternatively provided package file name must end with ``.rpm`` suffix.
-#
-#  .. note::
-#
-#    By using user provided spec file, rpm macro extensions such as for
-#    generating debuginfo packages or by simply using multiple components more
-#    than one rpm file may be generated, either from a single spec file or from
-#    multiple spec files (each component execution produces it's own spec file).
-#    In such cases duplicate file names may occur as a result of this variable
-#    setting or spec file content structure. Duplicate files get overwritten
-#    and it is up to the packager to set the variables in a manner that will
-#    prevent such errors.
-#
-# .. variable:: CPACK_RPM_MAIN_COMPONENT
-#
-#  Main component that is packaged without component suffix.
-#
-#  * Mandatory : NO
-#  * Default   : -
-#
-#  This variable can be set to any component or group name so that component or
-#  group rpm package is generated without component suffix in filename and
-#  package name.
-#
-# .. variable:: CPACK_RPM_PACKAGE_EPOCH
-#
-#  The RPM package epoch
-#
-#  * Mandatory : No
-#  * Default   : -
-#
-#  Optional number that should be incremented when changing versioning schemas
-#  or fixing mistakes in the version numbers of older packages.
-#
-# .. variable:: CPACK_RPM_PACKAGE_VERSION
-#
-#  The RPM package version.
-#
-#  * Mandatory : YES
-#  * Default   : :variable:`CPACK_PACKAGE_VERSION`
-#
-# .. variable:: CPACK_RPM_PACKAGE_ARCHITECTURE
-#               CPACK_RPM_<component>_PACKAGE_ARCHITECTURE
-#
-#  The RPM package architecture.
-#
-#  * Mandatory : YES
-#  * Default   : Native architecture output by ``uname -m``
-#
-#  This may be set to ``noarch`` if you know you are building a noarch package.
-#
-# .. variable:: CPACK_RPM_PACKAGE_RELEASE
-#
-#  The RPM package release.
-#
-#  * Mandatory : YES
-#  * Default   : 1
-#
-#  This is the numbering of the RPM package itself, i.e. the version of the
-#  packaging and not the version of the content (see
-#  :variable:`CPACK_RPM_PACKAGE_VERSION`). One may change the default value if
-#  the previous packaging was buggy and/or you want to put here a fancy Linux
-#  distro specific numbering.
-#
-# .. note::
-#
-#  This is the string that goes into the RPM ``Release:`` field. Some distros
-#  (e.g. Fedora, CentOS) require ``1%{?dist}`` format and not just a number.
-#  ``%{?dist}`` part can be added by setting :variable:`CPACK_RPM_PACKAGE_RELEASE_DIST`.
-#
-# .. variable:: CPACK_RPM_PACKAGE_RELEASE_DIST
-#
-#  The dist tag that is added  RPM ``Release:`` field.
-#
-#  * Mandatory : NO
-#  * Default   : OFF
-#
-#  This is the reported ``%{dist}`` tag from the current distribution or empty
-#  ``%{dist}`` if RPM macro is not set. If this variable is set then RPM
-#  ``Release:`` field value is set to ``${CPACK_RPM_PACKAGE_RELEASE}%{?dist}``.
-#
-# .. variable:: CPACK_RPM_PACKAGE_LICENSE
-#
-#  The RPM package license policy.
-#
-#  * Mandatory : YES

-#
-#  The RPM package vendor.
-#
-#  * Mandatory : YES
-#  * Default   : CPACK_PACKAGE_VENDOR if set or "unknown"

-#    if set or "no package description available"
-#
-# .. variable:: CPACK_RPM_COMPRESSION_TYPE
-#
-#  RPM compression type.
-#
-#  * Mandatory : NO
-#  * Default   : -
-#
-#  May be used to override RPM compression type to be used to build the
-#  RPM. For example some Linux distribution now default to lzma or xz
-#  compression whereas older cannot use such RPM. Using this one can enforce
-#  compression type to be used.
-#
-#  Possible values are:
-#
-#  - lzma
-#  - xz
-#  - bzip2
-#  - gzip
-#
-# .. variable:: CPACK_RPM_PACKAGE_AUTOREQ
-#               CPACK_RPM_<component>_PACKAGE_AUTOREQ
-#
-#  RPM spec autoreq field.
-#
-#  * Mandatory : NO
-#  * Default   : -
-#
-#  May be used to enable (1, yes) or disable (0, no) automatic shared libraries
-#  dependency detection. Dependencies are added to requires list.

-# .. variable:: CPACK_RPM_PACKAGE_AUTOPROV
-#               CPACK_RPM_<component>_PACKAGE_AUTOPROV
-#
-#  RPM spec autoprov field.

-#  * Mandatory : NO
-#  * Default   : CPACK_PACKAGE_RELOCATABLE
-#
-#  If this variable is set to TRUE or ON CPackRPM will try
-#  to build a relocatable RPM package. A relocatable RPM may
-#  be installed using::
-#
-#   rpm --prefix or --relocate
-#
-#  in order to install it at an alternate place see rpm(8). Note that
-#  currently this may fail if :variable:`CPACK_SET_DESTDIR` is set to ``ON``. If
-#  :variable:`CPACK_SET_DESTDIR` is set then you will get a warning message but
-#  if there is file installed with absolute path you'll get unexpected behavior.
-#
-# .. variable:: CPACK_RPM_SPEC_INSTALL_POST
-#
-#  Deprecated - use :variable:`CPACK_RPM_SPEC_MORE_DEFINE` instead.
-#
-#  * Mandatory : NO
-#  * Default   : -
-#  * Deprecated: YES
-#
-#  May be used to override the ``__spec_install_post`` section within the
-#  generated spec file.  This affects the install step during package creation,
-#  not during package installation.  For adding operations to be performed
-#  during package installation, use
-#  :variable:`CPACK_RPM_POST_INSTALL_SCRIPT_FILE` instead.
-#
-# .. variable:: CPACK_RPM_SPEC_MORE_DEFINE
-#
-#  RPM extended spec definitions lines.
-#
-#  * Mandatory : NO
-#  * Default   : -
-#
-#  May be used to add any ``%define`` lines to the generated spec file.  An
-#  example of its use is to prevent stripping of executables (but note that
-#  this may also disable other default post install processing)::
-#
-#    set(CPACK_RPM_SPEC_MORE_DEFINE "%define __spec_install_post /bin/true")
-#
-# .. variable:: CPACK_RPM_PACKAGE_DEBUG
-#
-#  Toggle CPackRPM debug output.
-#
-#  * Mandatory : NO
-#  * Default   : -
-#
-#  May be set when invoking cpack in order to trace debug information
-#  during CPack RPM run. For example you may launch CPack like this::
-#
-#   cpack -D CPACK_RPM_PACKAGE_DEBUG=1 -G RPM
-#
-# .. variable:: CPACK_RPM_USER_BINARY_SPECFILE
-#               CPACK_RPM_<componentName>_USER_BINARY_SPECFILE
-#
-#  A user provided spec file.
-#
-#  * Mandatory : NO
-#  * Default   : -
-#
-#  May be set by the user in order to specify a USER binary spec file
-#  to be used by CPackRPM instead of generating the file.
-#  The specified file will be processed by configure_file( @ONLY).
-#
-# .. variable:: CPACK_RPM_GENERATE_USER_BINARY_SPECFILE_TEMPLATE
-#
-#  Spec file template.
-#
-#  * Mandatory : NO
-#  * Default   : -
-#
-#  If set CPack will generate a template for USER specified binary
-#  spec file and stop with an error. For example launch CPack like this::
-#
-#   cpack -D CPACK_RPM_GENERATE_USER_BINARY_SPECFILE_TEMPLATE=1 -G RPM
-#
-#  The user may then use this file in order to hand-craft is own
-#  binary spec file which may be used with
-#  :variable:`CPACK_RPM_USER_BINARY_SPECFILE`.
-#
-# .. variable:: CPACK_RPM_PRE_INSTALL_SCRIPT_FILE
-#               CPACK_RPM_PRE_UNINSTALL_SCRIPT_FILE
-#
-#  Path to file containing pre (un)install script.
-#
-#  * Mandatory : NO
-#  * Default   : -
-#
-#  May be used to embed a pre (un)installation script in the spec file.
-#  The referred script file (or both) will be read and directly
-#  put after the ``%pre`` or ``%preun`` section
-#  If :variable:`CPACK_RPM_COMPONENT_INSTALL` is set to ON the (un)install
-#  script for each component can be overridden with
-#  ``CPACK_RPM_<COMPONENT>_PRE_INSTALL_SCRIPT_FILE`` and
-#  ``CPACK_RPM_<COMPONENT>_PRE_UNINSTALL_SCRIPT_FILE``.
-#  One may verify which scriptlet has been included with::
-#
-#   rpm -qp --scripts  package.rpm
-#
-# .. variable:: CPACK_RPM_POST_INSTALL_SCRIPT_FILE
-#               CPACK_RPM_POST_UNINSTALL_SCRIPT_FILE
-#
-#  Path to file containing post (un)install script.
-#
-#  * Mandatory : NO
-#  * Default   : -
-#
-#  May be used to embed a post (un)installation script in the spec file.
-#  The referred script file (or both) will be read and directly
-#  put after the ``%post`` or ``%postun`` section.
-#  If :variable:`CPACK_RPM_COMPONENT_INSTALL` is set to ON the (un)install
-#  script for each component can be overridden with
-#  ``CPACK_RPM_<COMPONENT>_POST_INSTALL_SCRIPT_FILE`` and
-#  ``CPACK_RPM_<COMPONENT>_POST_UNINSTALL_SCRIPT_FILE``.
-#  One may verify which scriptlet has been included with::
-#
-#   rpm -qp --scripts  package.rpm
-#
-# .. variable:: CPACK_RPM_USER_FILELIST
-#               CPACK_RPM_<COMPONENT>_USER_FILELIST
-#
-#  * Mandatory : NO
-#  * Default   : -
-#
-#  May be used to explicitly specify ``%(<directive>)`` file line
-#  in the spec file. Like ``%config(noreplace)`` or any other directive
-#  that be found in the ``%files`` section. You can have multiple directives
-#  per line, as in ``%attr(600,root,root) %config(noreplace)``. Since
-#  CPackRPM is generating the list of files (and directories) the user
-#  specified files of the ``CPACK_RPM_<COMPONENT>_USER_FILELIST`` list will
-#  be removed from the generated list. If referring to directories do
-#  not add a trailing slash.
-#
-# .. variable:: CPACK_RPM_CHANGELOG_FILE
-#
-#  RPM changelog file.
-#
-#  * Mandatory : NO
-#  * Default   : -
-#
-#  May be used to embed a changelog in the spec file.
-#  The referred file will be read and directly put after the ``%changelog``
-#  section.
-#
-# .. variable:: CPACK_RPM_EXCLUDE_FROM_AUTO_FILELIST
-#
-#  list of path to be excluded.
-#
-#  * Mandatory : NO
-#  * Default   : /etc /etc/init.d /usr /usr/bin /usr/include /usr/lib
-#                /usr/libx32 /usr/lib64 /usr/share /usr/share/aclocal
-#                /usr/share/doc
-#
-#  May be used to exclude path (directories or files) from the auto-generated
-#  list of paths discovered by CPack RPM. The default value contains a
-#  reasonable set of values if the variable is not defined by the user. If the
-#  variable is defined by the user then CPackRPM will NOT any of the default
-#  path. If you want to add some path to the default list then you can use
-#  :variable:`CPACK_RPM_EXCLUDE_FROM_AUTO_FILELIST_ADDITION` variable.
-#
-# .. variable:: CPACK_RPM_EXCLUDE_FROM_AUTO_FILELIST_ADDITION
-#
-#  additional list of path to be excluded.
-#
-#  * Mandatory : NO
-#  * Default   : -
-#
-#  May be used to add more exclude path (directories or files) from the initial
-#  default list of excluded paths. See
-#  :variable:`CPACK_RPM_EXCLUDE_FROM_AUTO_FILELIST`.
-#
-# .. variable:: CPACK_RPM_RELOCATION_PATHS
-#
-#  Packages relocation paths list.
-#
-#  * Mandatory : NO
-#  * Default   : -
-#
-#  May be used to specify more than one relocation path per relocatable RPM.
-#  Variable contains a list of relocation paths that if relative are prefixed
-#  by the value of :variable:`CPACK_RPM_<COMPONENT>_PACKAGE_PREFIX` or by the
-#  value of :variable:`CPACK_PACKAGING_INSTALL_PREFIX` if the component version
-#  is not provided.
-#  Variable is not component based as its content can be used to set a different
-#  path prefix for e.g. binary dir and documentation dir at the same time.
-#  Only prefixes that are required by a certain component are added to that
-#  component - component must contain at least one file/directory/symbolic link
-#  with :variable:`CPACK_RPM_RELOCATION_PATHS` prefix for a certain relocation
-#  path to be added. Package will not contain any relocation paths if there are
-#  no files/directories/symbolic links on any of the provided prefix locations.
-#  Packages that either do not contain any relocation paths or contain
-#  files/directories/symbolic links that are outside relocation paths print
-#  out an ``AUTHOR_WARNING`` that RPM will be partially relocatable.
-#
-# .. variable:: CPACK_RPM_<COMPONENT>_PACKAGE_PREFIX
-#
-#  Per component relocation path install prefix.
-#
-#  * Mandatory : NO
-#  * Default   : CPACK_PACKAGING_INSTALL_PREFIX
-#
-#  May be used to set per component :variable:`CPACK_PACKAGING_INSTALL_PREFIX`
-#  for relocatable RPM packages.
-#
-# .. variable:: CPACK_RPM_NO_INSTALL_PREFIX_RELOCATION
-#               CPACK_RPM_NO_<COMPONENT>_INSTALL_PREFIX_RELOCATION
-#
-#  Removal of default install prefix from relocation paths list.
-#
-#  * Mandatory : NO
-#  * Default   : CPACK_PACKAGING_INSTALL_PREFIX or CPACK_RPM_<COMPONENT>_PACKAGE_PREFIX
-#                are treated as one of relocation paths
-#
-#  May be used to remove CPACK_PACKAGING_INSTALL_PREFIX and CPACK_RPM_<COMPONENT>_PACKAGE_PREFIX
-#  from relocatable RPM prefix paths.
-#
-# .. variable:: CPACK_RPM_ADDITIONAL_MAN_DIRS
-#
-#  * Mandatory : NO
-#  * Default   : -
-#
-#  May be used to set additional man dirs that could potentially be compressed
-#  by brp-compress RPM macro. Variable content must be a list of regular
-#  expressions that point to directories containing man files or to man files
-#  directly. Note that in order to compress man pages a path must also be
-#  present in brp-compress RPM script and that brp-compress script must be
-#  added to RPM configuration by the operating system.
-#
-#  Regular expressions that are added by default were taken from brp-compress
-#  RPM macro:
-#
-#  - /usr/man/man.*
-#  - /usr/man/.*/man.*
-#  - /usr/info.*
-#  - /usr/share/man/man.*
-#  - /usr/share/man/.*/man.*
-#  - /usr/share/info.*
-#  - /usr/kerberos/man.*
-#  - /usr/X11R6/man/man.*
-#  - /usr/lib/perl5/man/man.*
-#  - /usr/share/doc/.*/man/man.*
-#  - /usr/lib/.*/man/man.*
-#
-# .. variable:: CPACK_RPM_DEFAULT_USER
-#               CPACK_RPM_<compName>_DEFAULT_USER
-#
-#  default user ownership of RPM content
-#
-#  * Mandatory : NO
-#  * Default   : root
-#
-#  Value should be user name and not UID.
-#  Note that <compName> must be in upper-case.
-#
-# .. variable:: CPACK_RPM_DEFAULT_GROUP
-#               CPACK_RPM_<compName>_DEFAULT_GROUP
-#
-#  default group ownership of RPM content
-#
-#  * Mandatory : NO
-#  * Default   : root
-#
-#  Value should be group name and not GID.
-#  Note that <compName> must be in upper-case.
-#
-# .. variable:: CPACK_RPM_DEFAULT_FILE_PERMISSIONS
-#               CPACK_RPM_<compName>_DEFAULT_FILE_PERMISSIONS
-#
-#  default permissions used for packaged files
-#
-#  * Mandatory : NO
-#  * Default   : - (system default)
-#
-#  Accepted values are lists with ``PERMISSIONS``. Valid permissions
-#  are:
-#
-#  - OWNER_READ
-#  - OWNER_WRITE
-#  - OWNER_EXECUTE
-#  - GROUP_READ
-#  - GROUP_WRITE
-#  - GROUP_EXECUTE
-#  - WORLD_READ
-#  - WORLD_WRITE
-#  - WORLD_EXECUTE
-#
-#  Note that <compName> must be in upper-case.
-#
-# .. variable:: CPACK_RPM_DEFAULT_DIR_PERMISSIONS
-#               CPACK_RPM_<compName>_DEFAULT_DIR_PERMISSIONS
-#
-#  default permissions used for packaged directories
-#
-#  * Mandatory : NO
-#  * Default   : - (system default)
-#
-#  Accepted values are lists with PERMISSIONS. Valid permissions
-#  are the same as for :variable:`CPACK_RPM_DEFAULT_FILE_PERMISSIONS`.
-#  Note that <compName> must be in upper-case.
-#
-# .. variable:: CPACK_RPM_INSTALL_WITH_EXEC
-#
-#  force execute permissions on programs and shared libraries
-#
-#  * Mandatory : NO
-#  * Default   : - (system default)
-#
-#  Force set owner, group and world execute permissions on programs and shared
-#  libraries. This can be used for creating valid rpm packages on systems such
-#  as Debian where shared libraries do not have execute permissions set.
-#
-# .. note::
-#
-#  Programs and shared libraries without execute permissions are ignored during
-#  separation of debug symbols from the binary for debuginfo packages.
-#
-# Packaging of Symbolic Links
-# ^^^^^^^^^^^^^^^^^^^^^^^^^^^
-#
-# CPackRPM supports packaging of symbolic links::
-#
-#   execute_process(COMMAND ${CMAKE_COMMAND}
-#     -E create_symlink <relative_path_location> <symlink_name>)
-#   install(FILES ${CMAKE_CURRENT_BINARY_DIR}/<symlink_name>
-#     DESTINATION <symlink_location> COMPONENT libraries)
-#
-# Symbolic links will be optimized (paths will be shortened if possible)
-# before being added to the package or if multiple relocation paths are
-# detected, a post install symlink relocation script will be generated.
-#
-# Symbolic links may point to locations that are not packaged by the same
-# package (either a different component or even not packaged at all) but
-# those locations will be treated as if they were a part of the package
-# while determining if symlink should be either created or present in a
-# post install script - depending on relocation paths.
-#
-# Symbolic links that point to locations outside packaging path produce a
-# warning and are treated as non relocatable permanent symbolic links.
-#
-# Currently there are a few limitations though:
-#
-# * For component based packaging component interdependency is not checked
-#   when processing symbolic links. Symbolic links pointing to content of
-#   a different component are treated the same way as if pointing to location
-#   that will not be packaged.
-#
-# * Symbolic links pointing to a location through one or more intermediate
-#   symbolic links will not be handled differently - if the intermediate
-#   symbolic link(s) is also on a relocatable path, relocating it during
-#   package installation may cause initial symbolic link to point to an
-#   invalid location.
-#
-# Packaging of debug information
-# ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-#
-# Debuginfo packages contain debug symbols and sources for debugging packaged
-# binaries.
-#
-# Debuginfo RPM packaging has it's own set of variables:
-#
-# .. variable:: CPACK_RPM_DEBUGINFO_PACKAGE
-#               CPACK_RPM_<component>_DEBUGINFO_PACKAGE
-#
-#  Enable generation of debuginfo RPM package(s).
-#
-#  * Mandatory : NO
-#  * Default   : OFF
-#
-# .. note::
-#
-#  Binaries must contain debug symbols before packaging so use either ``Debug``
-#  or ``RelWithDebInfo`` for :variable:`CMAKE_BUILD_TYPE` variable value.
-#
-# .. note::
-#
-#  Packages generated from packages without binary files, with binary files but
-#  without execute permissions or without debug symbols will cause packaging
-#  termination.
-#
-# .. variable:: CPACK_BUILD_SOURCE_DIRS
-#
-#  Provides locations of root directories of source files from which binaries
-#  were built.
-#
-#  * Mandatory : YES if :variable:`CPACK_RPM_DEBUGINFO_PACKAGE` is set
-#  * Default   : -
-#
-# .. note::
-#
-#  For CMake project :variable:`CPACK_BUILD_SOURCE_DIRS` is set by default to
-#  point to :variable:`CMAKE_SOURCE_DIR` and :variable:`CMAKE_BINARY_DIR` paths.
-#
-# .. note::
-#
-#  Sources with path prefixes that do not fall under any location provided with
-#  :variable:`CPACK_BUILD_SOURCE_DIRS` will not be present in debuginfo package.
-#
-# .. variable:: CPACK_RPM_BUILD_SOURCE_DIRS_PREFIX
-#               CPACK_RPM_<component>_BUILD_SOURCE_DIRS_PREFIX
-#
-#  Prefix of location where sources will be placed during package installation.
-#
-#  * Mandatory : YES if :variable:`CPACK_RPM_DEBUGINFO_PACKAGE` is set
-#  * Default   : "/usr/src/debug/<CPACK_PACKAGE_FILE_NAME>" and
-#                for component packaging "/usr/src/debug/<CPACK_PACKAGE_FILE_NAME>-<component>"
-#
-# .. note::
-#
-#  Each source path prefix is additionally suffixed by ``src_<index>`` where
-#  index is index of the path used from :variable:`CPACK_BUILD_SOURCE_DIRS`
-#  variable. This produces ``<CPACK_RPM_BUILD_SOURCE_DIRS_PREFIX>/src_<index>``
-#  replacement path.
-#  Limitation is that replaced path part must be shorter or of equal
-#  length than the length of its replacement. If that is not the case either
-#  :variable:`CPACK_RPM_BUILD_SOURCE_DIRS_PREFIX` variable has to be set to
-#  a shorter path or source directories must be placed on a longer path.
-#
-# .. variable:: CPACK_RPM_DEBUGINFO_EXCLUDE_DIRS
-#
-#  Directories containing sources that should be excluded from debuginfo packages.
-#
-#  * Mandatory : NO
-#  * Default   : "/usr /usr/src /usr/src/debug"
-#
-#  Listed paths are owned by other RPM packages and should therefore not be
-#  deleted on debuginfo package uninstallation.
-#
-# .. variable:: CPACK_RPM_DEBUGINFO_EXCLUDE_DIRS_ADDITION
-#
-#  Paths that should be appended to :variable:`CPACK_RPM_DEBUGINFO_EXCLUDE_DIRS`
-#  for exclusion.
-#
-#  * Mandatory : NO
-#  * Default   : -
-#
-# .. variable:: CPACK_RPM_DEBUGINFO_SINGLE_PACKAGE
-#
-#  Create a single debuginfo package even if components packaging is set.
-#
-#  * Mandatory : NO
-#  * Default   : OFF
-#
-#  When this variable is enabled it produces a single debuginfo package even if
-#  component packaging is enabled.
-#
-#  When using this feature in combination with components packaging and there is
-#  more than one component this variable requires :variable:`CPACK_RPM_MAIN_COMPONENT`
-#  to be set.
-#
-# .. note::
-#
-#  If none of the :variable:`CPACK_RPM_<component>_DEBUGINFO_PACKAGE` variables
-#  is set then :variable:`CPACK_RPM_DEBUGINFO_PACKAGE` is automatically set to
-#  ``ON`` when :variable:`CPACK_RPM_DEBUGINFO_SINGLE_PACKAGE` is set.
-#
-# .. variable:: CPACK_RPM_DEBUGINFO_FILE_NAME
-#               CPACK_RPM_<component>_DEBUGINFO_FILE_NAME
-#
-#  Debuginfo package file name.
-#
-#  * Mandatory : NO
-#  * Default   : rpmbuild tool generated package file name
-#
-#  Alternatively provided debuginfo package file name must end with ``.rpm``
-#  suffix and should differ from file names of other generated packages.
-#
-#  Variable may contain ``@cpack_component@`` placeholder which will be
-#  replaced by component name if component packaging is enabled otherwise it
-#  deletes the placeholder.
-#
-#  Setting the variable to ``RPM-DEFAULT`` may be used to explicitly set
-#  filename generation to default.
-#
-# .. note::
-#
-#  :variable:`CPACK_RPM_FILE_NAME` also supports rpmbuild tool generated package
-#  file name - disabled by default but can be enabled by setting the variable to
-#  ``RPM-DEFAULT``.
-#
-# Packaging of sources (SRPM)
-# ^^^^^^^^^^^^^^^^^^^^^^^^^^^
-#
-# SRPM packaging is enabled by setting :variable:`CPACK_RPM_PACKAGE_SOURCES`
-# variable while usually using :variable:`CPACK_INSTALLED_DIRECTORIES` variable
-# to provide directory containing CMakeLists.txt and source files.
-#
-# For CMake projects SRPM package would be produced by executing::
-#
-#   cpack -G RPM --config ./CPackSourceConfig.cmake
-#
-# .. note::
-#
-#  Produced SRPM package is expected to be built with :manual:`cmake(1)` executable
-#  and packaged with :manual:`cpack(1)` executable so CMakeLists.txt has to be
-#  located in root source directory and must be able to generate binary rpm
-#  packages by executing ``cpack -G`` command. The two executables as well as
-#  rpmbuild must also be present when generating binary rpm packages from the
-#  produced SRPM package.
-#
-# Once the SRPM package is generated it can be used to generate binary packages
-# by creating a directory structure for rpm generation and executing rpmbuild
-# tool::
-#
-#   mkdir -p build_dir/{BUILD,BUILDROOT,RPMS,SOURCES,SPECS,SRPMS}
-#   rpmbuild --define "_topdir <path_to_build_dir>" --rebuild <SRPM_file_name>
-#
-# Generated packages will be located in build_dir/RPMS directory or its sub
-# directories.
-#
-# .. note::
-#
-#  SRPM package internally uses CPack/RPM generator to generate binary packages
-#  so CMakeScripts.txt can decide during the SRPM to binary rpm generation step
-#  what content the package(s) should have as well as how they should be packaged
-#  (monolithic or components). CMake can decide this for e.g. by reading environment
-#  variables set by the package manager before starting the process of generating
-#  binary rpm packages. This way a single SRPM package can be used to produce
-#  different binary rpm packages on different platforms depending on the platform's
-#  packaging rules.
-#
-# Source RPM packaging has it's own set of variables:
-#
-# .. variable:: CPACK_RPM_PACKAGE_SOURCES
-#
-#  Should the content be packaged as a source rpm (default is binary rpm).
-#
-#  * Mandatory : NO
-#  * Default   : OFF
-#
-# .. note::
-#
-#  For cmake projects :variable:`CPACK_RPM_PACKAGE_SOURCES` variable is set
-#  to ``OFF`` in CPackConfig.cmake and ``ON`` in CPackSourceConfig.cmake
-#  generated files.
-#
-# .. variable:: CPACK_RPM_SOURCE_PKG_BUILD_PARAMS
-#
-#  Additional command-line parameters provided to :manual:`cmake(1)` executable.
-#
-#  * Mandatory : NO
-#  * Default   : -
-#
-# .. variable:: CPACK_RPM_SOURCE_PKG_PACKAGING_INSTALL_PREFIX
-#
-#  Packaging install prefix that would be provided in :variable:`CPACK_PACKAGING_INSTALL_PREFIX`
-#  variable for producing binary RPM packages.
-#
-#  * Mandatory : YES
-#  * Default   : "/"
-#
-# .. VARIABLE:: CPACK_RPM_BUILDREQUIRES
-#
-#  List of source rpm build dependencies.
-#
-#  * Mandatory : NO
-#  * Default   : -
-#
-#  May be used to set source RPM build dependencies (BuildRequires). Note that
-#  you must enclose the complete build requirements string between quotes, for
-#  example::
-#
-#   set(CPACK_RPM_BUILDREQUIRES "python >= 2.5.0, cmake >= 2.8")
