##section Variables specific to CPack Debian (DEB) generator
##end
##module
# - The builtin (binary) CPack Deb generator (Unix only)
# CPackDeb may be used to create Deb package using CPack.
# CPackDeb is a CPack generator thus it uses the CPACK_XXX variables
# used by CPack : http://www.cmake.org/Wiki/CMake:CPackConfiguration.
# 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 CPACK_DEBIAN_XXX variables.You'll find a detailed usage on
# the wiki:
#  http://www.cmake.org/Wiki/CMake:CPackPackageGenerators#DEB_.28UNIX_only.29
# However as a handy reminder here comes the list of specific variables:
##end
#
##variable
# CPACK_DEBIAN_PACKAGE_NAME
#     Mandatory : YES
#     Default   : CPACK_PACKAGE_NAME (lower case)
#     The debian package summary
##end
##variable
# CPACK_DEBIAN_PACKAGE_VERSION
#     Mandatory : YES
#     Default   : CPACK_PACKAGE_VERSION
#     The debian package version
##end
##variable
# CPACK_DEBIAN_PACKAGE_ARCHITECTURE
#     Mandatory : YES
#     Default   : Output of dpkg --print-architecture (or i386 if dpkg is not found)
#     The debian package architecture
##end
##variable
# CPACK_DEBIAN_PACKAGE_DEPENDS
#     Mandatory : NO
#     Default   : -
#     May be used to set deb dependencies.
##end
##variable
# CPACK_DEBIAN_PACKAGE_MAINTAINER
#     Mandatory : YES
#     Default   : CPACK_PACKAGE_CONTACT
#     The debian package maintainer
##end
##variable
# CPACK_DEBIAN_PACKAGE_DESCRIPTION
#     Mandatory : YES
#     Default   : CPACK_PACKAGE_DESCRIPTION_SUMMARY
#     The debian package description
##end
##variable
# CPACK_DEBIAN_PACKAGE_SECTION
#     Mandatory : YES
#     Default   : 'devel'
#     The debian package section
##end
##variable
# CPACK_DEBIAN_PACKAGE_PRIORITY
#     Mandatory : YES
#     Default   : 'optional'
#     The debian package priority
##end
##variable
# CPACK_DEBIAN_PACKAGE_HOMEPAGE
#     Mandatory : NO
#     Default   : -
#     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.
#     The content of this field is a simple URL without any surrounding
#     characters such as <>.
##end
##variable
# CPACK_DEBIAN_PACKAGE_SHLIBDEPS
#     Mandatory : NO
#     Default   : OFF
#     May be set to ON in order to use dpkg-shlibdeps to generate
#     better package dependency list.
#     You may need set CMAKE_INSTALL_RPATH toi appropriate value
#     if you use this feature, because if you don't dpkg-shlibdeps
#     may fail to find your own shared libs.
#     See http://www.cmake.org/Wiki/CMake_RPATH_handling.
##end
##variable
# CPACK_DEBIAN_PACKAGE_DEBUG
#     Mandatory : NO
#     Default   : -
#     May be set when invoking cpack in order to trace debug information
#     during CPackDeb run.
##end
##variable
# CPACK_DEBIAN_PACKAGE_PREDEPENDS
#     Mandatory : NO
#     Default   : -
#     see http://www.debian.org/doc/debian-policy/ch-relationships.html#s-binarydeps
#     This field is like Depends, except that it also forces dpkg to complete installation of
#     the packages named before even starting the installation of the package which declares
#     the pre-dependency.
##end
##variable
# CPACK_DEBIAN_PACKAGE_ENHANCES
#     Mandatory : NO
#     Default   : -
#     see http://www.debian.org/doc/debian-policy/ch-relationships.html#s-binarydeps
#     This field is similar to Suggests but works in the opposite direction.
#     It is used to declare that a package can enhance the functionality of another package.
##end
##variable
# CPACK_DEBIAN_PACKAGE_BREAKS
#     Mandatory : NO
#     Default   : -
#     see http://www.debian.org/doc/debian-policy/ch-relationships.html#s-binarydeps
#     When one binary package declares that it breaks another, dpkg will refuse to allow the
#     package which declares Breaks be installed unless the broken package is deconfigured first,
#     and it will refuse to allow the broken package to be reconfigured.
##end
##variable
# CPACK_DEBIAN_PACKAGE_CONFLICTS
#     Mandatory : NO
#     Default   : -
#     see http://www.debian.org/doc/debian-policy/ch-relationships.html#s-binarydeps
#     When one binary package declares a conflict with another using a Conflicts field,
#     dpkg will refuse to allow them to be installed on the system at the same time.
##end
##variable
# CPACK_DEBIAN_PACKAGE_PROVIDES
#     Mandatory : NO
#     Default   : -
#     see http://www.debian.org/doc/debian-policy/ch-relationships.html#s-binarydeps
#     A virtual package is one which appears in the Provides control field of another package.
##end
##variable
# CPACK_DEBIAN_PACKAGE_REPLACES
#     Mandatory : NO
#     Default   : -
#     see http://www.debian.org/doc/debian-policy/ch-relationships.html#s-binarydeps
#     Packages can declare in their control file that they should overwrite
#     files in certain other packages, or completely replace other packages.
##end
##variable
# CPACK_DEBIAN_PACKAGE_RECOMMENDS
#     Mandatory : NO
#     Default   : -
#     see http://www.debian.org/doc/debian-policy/ch-relationships.html#s-binarydeps
#     Allows packages to declare a strong, but not absolute, dependency on other packages.
##end
##variable
# CPACK_DEBIAN_PACKAGE_SUGGESTS
#     Mandatory : NO
#     Default   : -
#     see http://www.debian.org/doc/debian-policy/ch-relationships.html#s-binarydeps
#     Allows packages to declare a suggested package install grouping.
##end
##variable
# CPACK_DEBIAN_PACKAGE_CONTROL_EXTRA
#     Mandatory : NO
#     Default   : -
#     This variable allow advanced user to add custom script to the control.tar.gz
#     Typical usage is for conffiles, postinst, postrm, prerm.
#     Usage: set(CPACK_DEBIAN_PACKAGE_CONTROL_EXTRA
#            "${CMAKE_CURRENT_SOURCE_DIR/prerm;${CMAKE_CURRENT_SOURCE_DIR}/postrm")
