# 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 : https://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
# :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.
#
# You'll find a detailed usage on the wiki:
# https://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
# 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_PACKAGE_VERSION
#
# The Debian package version
#
# * Mandatory : YES
# * Default : :variable:`CPACK_PACKAGE_VERSION`
#
#
# .. variable:: CPACK_DEBIAN_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_PACKAGE_MAINTAINER
#
# The Debian package maintainer
#
# * Mandatory : YES
# * Default : :code:`CPACK_PACKAGE_CONTACT`
#
#
# .. variable:: CPACK_DEBIAN_PACKAGE_DESCRIPTION
# CPACK_COMPONENT_<COMPONENT>_DESCRIPTION

# CPACK_DEBIAN_<COMPONENT>_PACKAGE_SECTION
#
# Set Section control field e.g. admin, devel, doc, ...
#
# * Mandatory : YES
# * Default : 'devel'
#
# See https://www.debian.org/doc/debian-policy/ch-archive.html#s-subsections
#
#
# .. variable:: CPACK_DEBIAN_COMPRESSION_TYPE
#
# The compression used for creating the Debian package.
# Possible values are: lzma, xz, bzip2 and gzip.
#
# * Mandatory : YES
# * Default : 'gzip'
#
#
# .. variable:: CPACK_DEBIAN_PACKAGE_PRIORITY

# extra
#
# * Mandatory : YES
# * Default : 'optional'
#
# See https://www.debian.org/doc/debian-policy/ch-archive.html#s-priorities
#
#
# .. variable:: CPACK_DEBIAN_PACKAGE_HOMEPAGE

#
# * Mandatory : NO
# * Default : -

#
# The content of this field is a simple URL without any surrounding
# characters such as <>.
#
#
# .. variable:: CPACK_DEBIAN_PACKAGE_SHLIBDEPS
# CPACK_DEBIAN_<COMPONENT>_PACKAGE_SHLIBDEPS
#
# May be set to ON in order to use :code:`dpkg-shlibdeps` to generate
# better package dependency list.
#
# * Mandatory : NO
# * Default :
#
# - :variable:`CPACK_DEBIAN_PACKAGE_SHLIBDEPS` if set or
# - OFF
#
# .. note::
#
# You may need set :variable:`CMAKE_INSTALL_RPATH` to an appropriate value
# if you use this feature, because if you don't :code:`dpkg-shlibdeps`
# may fail to find your own shared libs.
# See https://cmake.org/Wiki/CMake_RPATH_handling.
#
#
# .. variable:: CPACK_DEBIAN_PACKAGE_DEBUG
#
# May be set when invoking cpack in order to trace debug information
# during CPackDeb run.
#
# * Mandatory : NO
# * Default : -
#
# .. variable:: CPACK_DEBIAN_PACKAGE_PREDEPENDS
# CPACK_DEBIAN_<COMPONENT>_PACKAGE_PREDEPENDS
#
# Sets the `Pre-Depends` field of the Debian package.

# also forces :code:`dpkg` to complete installation of the packages named
# before even starting the installation of the package which declares the
# pre-dependency.
#
# * Mandatory : NO
# * Default :
#
# - An empty string for non-component based installations
# - :variable:`CPACK_DEBIAN_PACKAGE_PREDEPENDS` for component-based
# installations.
#
# See http://www.debian.org/doc/debian-policy/ch-relationships.html#s-binarydeps
#
# .. variable:: CPACK_DEBIAN_PACKAGE_ENHANCES
# CPACK_DEBIAN_<COMPONENT>_PACKAGE_ENHANCES
#
# Sets the `Enhances` field of the Debian package.
# Similar to :variable:`Suggests <CPACK_DEBIAN_PACKAGE_SUGGESTS>` but works
# in the opposite direction: declares that a package can enhance the
# functionality of another package.
#
# * Mandatory : NO
# * Default :
#
# - An empty string for non-component based installations
# - :variable:`CPACK_DEBIAN_PACKAGE_ENHANCES` for component-based
# installations.
#
# See http://www.debian.org/doc/debian-policy/ch-relationships.html#s-binarydeps
#
# .. variable:: CPACK_DEBIAN_PACKAGE_BREAKS
# CPACK_DEBIAN_<COMPONENT>_PACKAGE_BREAKS
#
# Sets the `Breaks` field of the Debian package.
# When a binary package (P) declares that it breaks other packages (B),
# :code:`dpkg` will not allow the package (P) which declares `Breaks` be
# **unpacked** unless the packages that will be broken (B) are deconfigured
# first.
# As long as the package (P) is configured, the previously deconfigured
# packages (B) cannot be reconfigured again.
#
# * Mandatory : NO
# * Default :
#
# - An empty string for non-component based installations
# - :variable:`CPACK_DEBIAN_PACKAGE_BREAKS` for component-based
# installations.
#
# See https://www.debian.org/doc/debian-policy/ch-relationships.html#s-breaks
#
#
# .. variable:: CPACK_DEBIAN_PACKAGE_CONFLICTS
# CPACK_DEBIAN_<COMPONENT>_PACKAGE_CONFLICTS
#
# Sets the `Conflicts` field of the Debian package.
# When one binary package declares a conflict with another using a `Conflicts`
# field, :code:`dpkg` will not allow them to be unpacked on the system at
# the same time.
#
# * Mandatory : NO
# * Default :
#
# - An empty string for non-component based installations
# - :variable:`CPACK_DEBIAN_PACKAGE_CONFLICTS` for component-based
# installations.
#
# See https://www.debian.org/doc/debian-policy/ch-relationships.html#s-conflicts
#
# .. note::
#
# This is a stronger restriction than
# :variable:`Breaks <CPACK_DEBIAN_PACKAGE_BREAKS>`, which prevents the
# broken package from being configured while the breaking package is in
# the "Unpacked" state but allows both packages to be unpacked at the same
# time.
#
# .. variable:: CPACK_DEBIAN_PACKAGE_PROVIDES
# CPACK_DEBIAN_<COMPONENT>_PACKAGE_PROVIDES
#
# Sets the `Provides` field of the Debian package.
# A virtual package is one which appears in the `Provides` control field of
# another package.
#
# * Mandatory : NO
# * Default :
#
# - An empty string for non-component based installations
# - :variable:`CPACK_DEBIAN_PACKAGE_PROVIDES` for component-based
# installations.
#
# See https://www.debian.org/doc/debian-policy/ch-relationships.html#s-virtual
#
#
# .. variable:: CPACK_DEBIAN_PACKAGE_REPLACES
# CPACK_DEBIAN_<COMPONENT>_PACKAGE_REPLACES

# - An empty string for non-component based installations
# - :variable:`CPACK_DEBIAN_PACKAGE_REPLACES` for component-based
# installations.
#
# See http://www.debian.org/doc/debian-policy/ch-relationships.html#s-binarydeps
#
#
# .. variable:: CPACK_DEBIAN_PACKAGE_RECOMMENDS
# CPACK_DEBIAN_<COMPONENT>_PACKAGE_RECOMMENDS
#
# Sets the `Recommends` field of the Debian package.
# Allows packages to declare a strong, but not absolute, dependency on other
# packages.
#
# * Mandatory : NO
# * Default :
#
# - An empty string for non-component based installations
# - :variable:`CPACK_DEBIAN_PACKAGE_RECOMMENDS` for component-based
# installations.
#
# See http://www.debian.org/doc/debian-policy/ch-relationships.html#s-binarydeps
#
#
# .. variable:: CPACK_DEBIAN_PACKAGE_SUGGESTS
# CPACK_DEBIAN_<COMPONENT>_PACKAGE_SUGGESTS

#
# Usage::
#
# set(CPACK_DEBIAN_PACKAGE_CONTROL_EXTRA
# "${CMAKE_CURRENT_SOURCE_DIR/prerm;${CMAKE_CURRENT_SOURCE_DIR}/postrm")
#
# .. note::
#
# The original permissions of the files will be used in the final
# package unless the variable
# :variable:`CPACK_DEBIAN_PACKAGE_CONTROL_STRICT_PERMISSION` is set.
# In particular, the scripts should have the proper executable
# flag prior to the generation of the package.
#
# .. variable:: CPACK_DEBIAN_PACKAGE_CONTROL_STRICT_PERMISSION
# CPACK_DEBIAN_<COMPONENT>_PACKAGE_CONTROL_STRICT_PERMISSION
#
# This variable indicates if the Debian policy on control files should be
# strictly followed.
#
# * Mandatory : NO
# * Default : FALSE
#
# Usage::
#
# set(CPACK_DEBIAN_PACKAGE_CONTROL_STRICT_PERMISSION TRUE)
#
# .. note::
#
# This overrides the permissions on the original files, following the rules

# indicated with the field ``Source``.
#
# * Mandatory : NO
# * Default :
#
# - An empty string for non-component based installations
