# - Build binary and source package installers
#
# The CPack module generates binary and source installers in a variety
# of formats using the cpack program. Inclusion of the CPack module
# adds two new targets to the resulting makefiles, package and
# package_source, which build the binary and source installers,
# respectively. The generated binary installers contain everything
# installed via CMake's INSTALL command (and the deprecated
# INSTALL_FILES, INSTALL_PROGRAMS, and INSTALL_TARGETS commands).
#
# For certain kinds of binary installers (including the graphical
# installers on Mac OS X and Windows), CPack generates installers that
# allow users to select individual application components to
# install. See CPackComponent module for that.
#
# The CPACK_GENERATOR variable has different meanings in different
# contexts. In your CMakeLists.txt file, CPACK_GENERATOR is a
# *list of generators*: when run with no other arguments, CPack
# will iterate over that list and produce one package for each
# generator. In a CPACK_PROJECT_CONFIG_FILE, though, CPACK_GENERATOR
# is a *string naming a single generator*. If you need per-cpack-
# generator logic to control *other* cpack settings, then you need
# a CPACK_PROJECT_CONFIG_FILE.
#
# The CMake source tree itself contains a CPACK_PROJECT_CONFIG_FILE.
# See the top level file CMakeCPackOptions.cmake.in for an example.
#
# If set, the CPACK_PROJECT_CONFIG_FILE is included automatically
# on a per-generator basis. It only need contain overrides.
#
# Here's how it works:
# - cpack runs
# - it includes CPackConfig.cmake
# - it iterates over the generators listed in that file's
#     CPACK_GENERATOR list variable (unless told to use just a
#     specific one via -G on the command line...)
#
# - foreach generator, it then
#   - sets CPACK_GENERATOR to the one currently being iterated
#   - includes the CPACK_PROJECT_CONFIG_FILE
#   - produces the package for that generator
#
# This is the key: For each generator listed in CPACK_GENERATOR
# in CPackConfig.cmake, cpack will *reset* CPACK_GENERATOR
# internally to *the one currently being used* and then include
# the CPACK_PROJECT_CONFIG_FILE.
#
# Before including this CPack module in your CMakeLists.txt file,
# there are a variety of variables that can be set to customize
# the resulting installers. The most commonly-used variables are:
#
#   CPACK_PACKAGE_NAME - The name of the package (or application). If
#   not specified, defaults to the project name.
#
#   CPACK_PACKAGE_VENDOR - The name of the package vendor (e.g.,
#   "Kitware").
#
#   CPACK_PACKAGE_VERSION_MAJOR - Package major Version
#
#   CPACK_PACKAGE_VERSION_MINOR - Package minor Version
#
#   CPACK_PACKAGE_VERSION_PATCH - Package patch Version
#
#   CPACK_PACKAGE_DESCRIPTION_FILE - A text file used to describe the
#   project. Used, for example, the introduction screen of a
#   CPack-generated Windows installer to describe the project.
#
#   CPACK_PACKAGE_DESCRIPTION_SUMMARY - Short description of the
#   project (only a few words).
#
#   CPACK_PACKAGE_FILE_NAME - The name of the package file to generate,
#   not including the extension. For example, cmake-2.6.1-Linux-i686.
#
#   CPACK_PACKAGE_INSTALL_DIRECTORY - Installation directory on the
#   target system, e.g., "CMake 2.5".
#
#   CPACK_PROJECT_CONFIG_FILE - File included at cpack time, once per
#   generator after setting CPACK_GENERATOR to the actual generator
#   being used. Allows per-generator setting of CPACK_* variables at
#   cpack time.
#
#   CPACK_RESOURCE_FILE_LICENSE - License file for the project, which
#   will typically be displayed to the user (often with an explicit
#   "Accept" button, for graphical installers) prior to installation.
#
#   CPACK_RESOURCE_FILE_README - ReadMe file for the project, which
#   typically describes in some detail
#
#   CPACK_RESOURCE_FILE_WELCOME - Welcome file for the project, which
#   welcomes users to this installer. Typically used in the graphical
#   installers on Windows and Mac OS X.
#
#   CPACK_MONOLITHIC_INSTALL - Disables the component-based 
#   installation mechanism, so that all components are always installed.
#
#   CPACK_GENERATOR - List of CPack generators to use. If not
#   specified, CPack will create a set of options (e.g.,
#   CPACK_BINARY_NSIS) allowing the user to enable/disable individual
#   generators.
#
#   CPACK_OUTPUT_CONFIG_FILE - The name of the CPack configuration file
#   for binary installers that will be generated by the CPack
#   module. Defaults to CPackConfig.cmake.
#
#   CPACK_PACKAGE_EXECUTABLES - Lists each of the executables along
#   with a text label, to be used to create Start Menu shortcuts on
#   Windows. For example, setting this to the list ccmake;CMake will
#   create a shortcut named "CMake" that will execute the installed
#   executable ccmake.
#
#   CPACK_STRIP_FILES - List of files to be stripped. Starting with
#   CMake 2.6.0 CPACK_STRIP_FILES will be a boolean variable which
#   enables stripping of all files (a list of files evaluates to TRUE
#   in CMake, so this change is compatible).
#
# The following CPack variables are specific to source packages, and 
# will not affect binary packages:
#
#   CPACK_SOURCE_PACKAGE_FILE_NAME - The name of the source package,
#   e.g., cmake-2.6.1
#
#   CPACK_SOURCE_STRIP_FILES - List of files in the source tree that
#   will be stripped. Starting with CMake 2.6.0
#   CPACK_SOURCE_STRIP_FILES will be a boolean variable which enables
#   stripping of all files (a list of files evaluates to TRUE in CMake,
#   so this change is compatible).
#
#   CPACK_SOURCE_GENERATOR - List of generators used for the source
#   packages. As with CPACK_GENERATOR, if this is not specified then
#   CPack will create a set of options (e.g., CPACK_SOURCE_ZIP)
#   allowing users to select which packages will be generated.
#
#   CPACK_SOURCE_OUTPUT_CONFIG_FILE - The name of the CPack
#   configuration file for source installers that will be generated by
#   the CPack module. Defaults to CPackSourceConfig.cmake.
#
#   CPACK_SOURCE_IGNORE_FILES - Pattern of files in the source tree
#   that won't be packaged when building a source package. This is a
#   list of patterns, e.g., /CVS/;/\\.svn/;\\.swp$;\\.#;/#;.*~;cscope.*
#
# The following variables are specific to the DragNDrop installers
# built on Mac OS X:
#
#   CPACK_DMG_VOLUME_NAME - The volume name of the generated disk
#   image. Defaults to CPACK_PACKAGE_FILE_NAME.
#
#   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.
#
#   CPACK_DMG_DS_STORE - Path to a custom .DS_Store file which 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 OSA-script) using a normal folder from which the .DS_Store
#   file can then be extracted.
#
#   CPACK_DMG_BACKGROUND_IMAGE - Path to an image file which is to be
#   used as the background for the Finder Window when the disk image
#   is opened.  By default no background image is set. The background
#   image is applied after applying the custom .DS_Store file.
#
#   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.)
#
#   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.)
#
#   CPACK_COMMAND_REZ - Path to the Rez(1) command used to compile
#   resources 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.)
#
# The following variable is specific to installers build on Mac OS X
# using PackageMaker:
#
#   CPACK_OSX_PACKAGE_VERSION - The version of Mac OS X that the
#   resulting PackageMaker archive should be compatible
#   with. Different versions of Mac OS X support different
#   features. For example, CPack can only build component-based
#   installers for Mac OS X 10.4 or newer, and can only build
#   installers that download component son-the-fly for Mac OS X 10.5
#   or newer. If left blank, this value will be set to the minimum
#   version of Mac OS X that supports the requested features. Set this
#   variable to some value (e.g., 10.4) only if you want to guarantee
#   that your installer will work on that version of Mac OS X, and
#   don't mind missing extra features available in the installer
#   shipping with later versions of Mac OS X.
#
# The following variables are for advanced uses of CPack:
#
#   CPACK_CMAKE_GENERATOR - What CMake generator should be used if the
#   project is CMake project. Defaults to the value of CMAKE_GENERATOR;
#   few users will want to change this setting.
#
#   CPACK_INSTALL_CMAKE_PROJECTS - List of four values that specify
#   what project to install. The four values are: Build directory,
#   Project Name, Project Component, Directory. If omitted, CPack will
#   build an installer that installers everything.
#
#   CPACK_SYSTEM_NAME - System name, defaults to the value of
#   ${CMAKE_SYSTEM_NAME}.
#
#   CPACK_PACKAGE_VERSION - Package full version, used internally. By
#   default, this is built from CPACK_PACKAGE_VERSION_MAJOR,
#   CPACK_PACKAGE_VERSION_MINOR, and CPACK_PACKAGE_VERSION_PATCH.
#
#   CPACK_TOPLEVEL_TAG - Directory for the installed files.
#
#   CPACK_INSTALL_COMMANDS - Extra commands to install components.
#
#   CPACK_INSTALL_DIRECTORIES - Extra directories to install.
