# CPackDeb
# --------
#
# The builtin (binary) CPack Deb generator (Unix only)
#
# Variables specific to CPack Debian (DEB) generator
# ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
#
# 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:
#
# .. variable:: CPACK_DEBIAN_PACKAGE_NAME
#
# * Mandatory : YES
# * Default : CPACK_PACKAGE_NAME (lower case)
#
# The debian package summary
#
# .. variable:: CPACK_DEBIAN_PACKAGE_VERSION
#
# * Mandatory : YES
# * Default : CPACK_PACKAGE_VERSION
#
# The debian package version
#
# .. variable:: CPACK_DEBIAN_PACKAGE_ARCHITECTURE
#
# * Mandatory : YES
# * Default : Output of dpkg --print-architecture (or i386 if dpkg is not found)
#
# The debian package architecture
#
# .. variable:: CPACK_DEBIAN_PACKAGE_DEPENDS
#
# * Mandatory : NO
# * Default : -
#
# May be used to set deb dependencies.
#
# .. variable:: CPACK_DEBIAN_PACKAGE_MAINTAINER
#
# * Mandatory : YES
# * Default : CPACK_PACKAGE_CONTACT
#
# The debian package maintainer
#
# .. variable:: CPACK_DEBIAN_PACKAGE_DESCRIPTION
#
# * Mandatory : YES
# * Default : CPACK_PACKAGE_DESCRIPTION_SUMMARY
#
# The debian package description
#
# .. variable:: CPACK_DEBIAN_PACKAGE_SECTION
#
# * Mandatory : YES
# * Default : 'devel'
#
# The debian package section
#
# .. variable:: CPACK_DEBIAN_PACKAGE_PRIORITY
#
# * Mandatory : YES
# * Default : 'optional'
#
# The debian package priority
#
# .. 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 <>.
#
# .. 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.
#
# .. variable:: CPACK_DEBIAN_PACKAGE_DEBUG
#
# * Mandatory : NO
# * Default : -
#
# May be set when invoking cpack in order to trace debug information
# during CPackDeb run.
#
# .. 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.
#
# .. 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.
#
# .. 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.
#
# .. 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.
#
# .. 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.
#
# .. 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.
#
# .. 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.
#
# .. 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.
#
# .. 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")
