# 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# are no longer maintained but may still prove useful: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`

#
#
# .. variable:: CPACK_DEBIAN_PACKAGE_SECTION
# 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_ARCHIVE_TYPE
#
# The archive format used for creating the Debian package.
#
# * Mandatory : YES
# * Default : "paxr"
#
# Possible values are:
#
# - paxr
# - gnutar
#
# .. note::
#
# Default pax archive format is the most portable format and generates
# packages that do not treat sparse files specially.
# GNU tar format on the other hand supports longer filenames.
#
# .. variable:: CPACK_DEBIAN_COMPRESSION_TYPE
#
# The compression used for creating the Debian package.
#
# * Mandatory : YES
# * Default : "gzip"
#
# Possible values are:

#
# .. variable:: CPACK_DEBIAN_PACKAGE_HOMEPAGE
#
# 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 : NO
# * Default : :variable:`CMAKE_PROJECT_HOMEPAGE_URL`
#
# .. note::
#
# 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://gitlab.kitware.com/cmake/community/wikis/doc/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.
# Like :variable:`Depends <CPACK_DEBIAN_PACKAGE_DEPENDS>`, except that it
# 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.

#
# - 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
#

#
# .. variable:: CPACK_DEBIAN_PACKAGE_GENERATE_SHLIBS_POLICY
#
# Compatibility policy for auto-generated shlibs control file.
#
# * Mandatory : NO
# * Default : "="
#
# Defines compatibility policy for auto-generated shlibs control file.

#
# 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

#
# .. 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

# * Default : FALSE
#
# Usage::
#
# set(CPACK_DEBIAN_PACKAGE_CONTROL_STRICT_PERMISSION TRUE)
#
# .. note::
#
# This overrides the permissions on the original files, following the rules

# https://www.debian.org/doc/debian-policy/ch-files.html#s-permissions-owners
#
# .. variable:: CPACK_DEBIAN_PACKAGE_SOURCE
# CPACK_DEBIAN_<COMPONENT>_PACKAGE_SOURCE
#
# Sets the ``Source`` field of the binary Debian package.

#
# * Mandatory : NO
# * Default :
#
# - An empty string for non-component based installations
