# 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# are no longer maintained but may still prove useful: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://cmake.org/Wiki/CMake:CPackConfiguration
#  - https://cmake.org/Wiki/CMake:CPackPackageGenerators#DEB_.28UNIX_only.29
#
# List of CPackRPM specific variables:
#
# .. variable:: CPACK_DEB_PACKAGE_COMPONENT
#
#  Enable component packaging for CPackRPM
#
#  * 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 ``.deb`` 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_VERSION
#
#  The Debian package version
#
#  * Mandatory : YES
#  * Default   : :variable:`CPACK_PACKAGE_VERSION`
#
# .. variable:: CPACK_DEBIAN_PACKAGE_RELEASE
#
#  The Debian package release - Debian revision number.
#
#  * Mandatory : YES
#  * Default   : 1
#
#  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_DESCRIPTION
#               CPACK_COMPONENT_<COMPONENT>_DESCRIPTION
#
#  The Debian package description

#
#    - :variable:`CPACK_DEBIAN_PACKAGE_DESCRIPTION` if set or
#    - :variable:`CPACK_PACKAGE_DESCRIPTION_SUMMARY`
#
#
# .. 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_COMPRESSION_TYPE
#
#  The compression used for creating the Debian package.
#
#  * Mandatory : YES
#  * Default   : "gzip"
#
#  Possible values are:

#  - bzip2
#  - gzip
#
# .. variable:: CPACK_DEBIAN_PACKAGE_PRIORITY
#               CPACK_DEBIAN_<COMPONENT>_PACKAGE_PRIORITY
#
#  Set Priority control field e.g. required, important, standard, optional,
#  extra

#
# .. 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   : -
#
#  .. 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://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.

#  * 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.
#
#  See https://www.debian.org/doc/debian-policy/ch-relationships.html#s-virtual
#
# .. variable:: CPACK_DEBIAN_PACKAGE_REPLACES
#               CPACK_DEBIAN_<COMPONENT>_PACKAGE_REPLACES
#
#  Sets the `Replaces` field of the Debian package.
#  Packages can declare in their control file that they should overwrite
#  files in certain other packages, or completely replace other packages.
#
#  * Mandatory : NO
#  * Default   :
#
#    - 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.

#  Sets the `Suggests` field of the Debian package.
#  Allows packages to declare a suggested package install grouping.
#
#  * Mandatory : NO
#  * Default   :
#
#    - An empty string for non-component based installations
#    - :variable:`CPACK_DEBIAN_PACKAGE_SUGGESTS` for component-based

#
#  See http://www.debian.org/doc/debian-policy/ch-relationships.html#s-binarydeps
#
# .. variable:: CPACK_DEBIAN_PACKAGE_GENERATE_SHLIBS
#
#  * Mandatory : NO
#  * Default   : OFF
#
#  Allows to generate shlibs control file automatically. Compatibility is defined by
#  :variable:`CPACK_DEBIAN_PACKAGE_GENERATE_SHLIBS_POLICY` variable value.
#
#  .. note::
#
#    Libraries are only considered if they have both library name and version
#    set. This can be done by setting SOVERSION property with
#    :command:`set_target_properties` command.
#
# .. variable:: CPACK_DEBIAN_PACKAGE_GENERATE_SHLIBS_POLICY
#
#  Compatibility policy for auto-generated shlibs control file.

#               CPACK_DEBIAN_<COMPONENT>_PACKAGE_CONTROL_EXTRA
#
#  This variable allow advanced user to add custom script to the
#  control.tar.gz.
#  Typical usage is for conffiles, postinst, postrm, prerm.
#
#  * Mandatory : NO
#  * Default   : -
#
#  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::

#
#  Sets the ``Source`` field of the binary Debian package.
#  When the binary package name is not the same as the source package name
#  (in particular when several components/binaries are generated from one
#  source) the source from which the binary has been generated should be
#  indicated with the field ``Source``.
#
#  * Mandatory : NO
#  * Default   :
#
#    - An empty string for non-component based installations
#    - :variable:`CPACK_DEBIAN_PACKAGE_SOURCE` for component-based
#      installations.
#
#  See https://www.debian.org/doc/debian-policy/ch-controlfields.html#s-f-Source
#
#  .. note::
#
#    This value is not interpreted. It is possible to pass an optional
