CPack
-----

Configure generators for binary installers and source packages.

Introduction
^^^^^^^^^^^^

The CPack module generates the configuration files ``CPackConfig.cmake``
and ``CPackSourceConfig.cmake``. They are intended for use in a subsequent
run of  the :manual:`cpack <cpack(1)>` program where they steer the generation
of installers or/and source packages.

Depending on the CMake generator, the CPack module may also add two new build
targets, ``package`` and ``package_source``. See the `packaging targets`_
section below for details.

The generated binary installers will contain all files that have been installed
via CMake's :command:`install` command (and the deprecated commands
:command:`install_files`, :command:`install_programs`, and
:command:`install_targets`). Note that the ``DESTINATION`` option of the
:command:`install` command must be a relative path; otherwise installed files
are ignored by CPack.

Certain kinds of binary installers can be configured such that users can select
individual application components to install.  See the :module:`CPackComponent`
module for further details.

Source packages (configured through ``CPackSourceConfig.cmake`` and generated
by the :cpack_gen:`CPack Archive Generator`) will contain all source files in
the project directory except those specified in
:variable:`CPACK_SOURCE_IGNORE_FILES`.

CPack Generators
^^^^^^^^^^^^^^^^

The :variable:`CPACK_GENERATOR` variable has different meanings in different
contexts.  In a ``CMakeLists.txt`` file, :variable:`CPACK_GENERATOR` is a
*list of generators*: and when :manual:`cpack <cpack(1)>` is run with no other
arguments, it will iterate over that list and produce one package for each
generator.  In a :variable:`CPACK_PROJECT_CONFIG_FILE`,
:variable:`CPACK_GENERATOR` is a *string naming a single generator*.  If you
need per-cpack-generator logic to control *other* cpack settings, then you
need a :variable:`CPACK_PROJECT_CONFIG_FILE`.
If set, the :variable:`CPACK_PROJECT_CONFIG_FILE` is included automatically
on a per-generator basis.  It only need contain overrides.

Here's how it works:

* :manual:`cpack <cpack(1)>` runs
* it includes ``CPackConfig.cmake``
* it iterates over the generators given by the ``-G`` command line option,
  or if no such option was specified, over the list of generators given by
  the :variable:`CPACK_GENERATOR` variable set in the ``CPackConfig.cmake``
  input file.
* foreach generator, it then

  - sets :variable:`CPACK_GENERATOR` to the one currently being iterated
  - includes the :variable:`CPACK_PROJECT_CONFIG_FILE`
  - produces the package for that generator

This is the key: For each generator listed in :variable:`CPACK_GENERATOR` in
``CPackConfig.cmake``, cpack will *reset* :variable:`CPACK_GENERATOR`
internally to *the one currently being used* and then include the
:variable:`CPACK_PROJECT_CONFIG_FILE`.

For a list of available generators, see :manual:`cpack-generators(7)`.

.. _`packaging targets`:

Targets package and package_source
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

If CMake is run with the Makefile, Ninja, or Xcode generator, then
``include(CPack)`` generates a target ``package``. This makes it possible
to build a binary installer from CMake, Make, or Ninja: Instead of ``cpack``,
one may call ``cmake --build . --target package`` or ``make package`` or
``ninja package``. The VS generator creates an uppercase target ``PACKAGE``.

If CMake is run with the Makefile or Ninja generator, then ``include(CPack)``
also generates a target ``package_source``. To build a source package,
instead of ``cpack -G TGZ --config CPackSourceConfig.cmake`` one may call
``cmake --build . --target package_source``, ``make package_source``,
or ``ninja package_source``.


Variables common to all CPack Generators
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Before including this CPack module in your ``CMakeLists.txt`` file, there
are a variety of variables that can be set to customize the resulting
installers.  The most commonly-used variables are:

.. variable:: CPACK_PACKAGE_NAME

  The name of the package (or application).  If not specified, it defaults to
  the project name.

.. variable:: CPACK_PACKAGE_VENDOR

  The name of the package vendor. (e.g., "Kitware").  The default is "Humanity".

.. variable:: CPACK_PACKAGE_DIRECTORY

  The directory in which CPack is doing its packaging.  If it is not set
  then this will default (internally) to the build dir.  This variable may
  be defined in a CPack config file or from the :manual:`cpack <cpack(1)>`
  command line option ``-B``.  If set, the command line option overrides the
  value found in the config file.

.. variable:: CPACK_PACKAGE_VERSION_MAJOR

  Package major version.  This variable will always be set, but its default
  value depends on whether or not version details were given to the
  :command:`project` command in the top level CMakeLists.txt file.  If version
  details were given, the default value will be
  :variable:`CMAKE_PROJECT_VERSION_MAJOR`.  If no version details were given,
  a default version of 0.1.1 will be assumed, leading to
  ``CPACK_PACKAGE_VERSION_MAJOR`` having a default value of 0.

.. variable:: CPACK_PACKAGE_VERSION_MINOR

  Package minor version.  The default value is determined based on whether or
  not version details were given to the :command:`project` command in the top
  level CMakeLists.txt file.  If version details were given, the default
  value will be :variable:`CMAKE_PROJECT_VERSION_MINOR`, but if no minor
  version component was specified then ``CPACK_PACKAGE_VERSION_MINOR`` will be
  left unset.  If no project version was given at all, a default version of
  0.1.1 will be assumed, leading to ``CPACK_PACKAGE_VERSION_MINOR`` having a
  default value of 1.

.. variable:: CPACK_PACKAGE_VERSION_PATCH

  Package patch version.  The default value is determined based on whether or
  not version details were given to the :command:`project` command in the top
  level CMakeLists.txt file.  If version details were given, the default
  value will be :variable:`CMAKE_PROJECT_VERSION_PATCH`, but if no patch
  version component was specified then ``CPACK_PACKAGE_VERSION_PATCH`` will be
  left unset.  If no project version was given at all, a default version of
  0.1.1 will be assumed, leading to ``CPACK_PACKAGE_VERSION_PATCH`` having a
  default value of 1.

.. variable:: CPACK_PACKAGE_DESCRIPTION

  A description of the project, used in places such as the introduction
  screen of CPack-generated Windows installers.  If not set, the value of
  this variable is populated from the file named by
  :variable:`CPACK_PACKAGE_DESCRIPTION_FILE`.

.. variable:: CPACK_PACKAGE_DESCRIPTION_FILE

  A text file used to describe the project when
  :variable:`CPACK_PACKAGE_DESCRIPTION` is not explicitly set.  The default
  value for ``CPACK_PACKAGE_DESCRIPTION_FILE`` points to a built-in template
  file ``Templates/CPack.GenericDescription.txt``.

.. variable:: CPACK_PACKAGE_DESCRIPTION_SUMMARY

  Short description of the project (only a few words).  If the
  :variable:`CMAKE_PROJECT_DESCRIPTION` variable is set, it is used as the
  default value, otherwise the default will be a string generated by CMake
  based on :variable:`CMAKE_PROJECT_NAME`.

.. variable:: CPACK_PACKAGE_HOMEPAGE_URL

  Project homepage URL.  The default value is taken from the
  :variable:`CMAKE_PROJECT_HOMEPAGE_URL` variable, which is set by the top
  level :command:`project` command, or else the default will be empty if no
  URL was provided to :command:`project`.

.. variable:: CPACK_PACKAGE_FILE_NAME

  The name of the package file to generate, not including the
  extension.  For example, ``cmake-2.6.1-Linux-i686``.  The default value
  is::

    ${CPACK_PACKAGE_NAME}-${CPACK_PACKAGE_VERSION}-${CPACK_SYSTEM_NAME}

.. variable:: CPACK_PACKAGE_INSTALL_DIRECTORY

  Installation directory on the target system. This may be used by some
  CPack generators like NSIS to create an installation directory e.g.,
  "CMake 2.5" below the installation prefix.  All installed elements will be
  put inside this directory.

.. variable:: CPACK_PACKAGE_ICON

  A branding image that will be displayed inside the installer (used by GUI
  installers).

.. variable:: CPACK_PACKAGE_CHECKSUM

  .. versionadded:: 3.7

  An algorithm that will be used to generate an additional file with the
  checksum of the package.  The output file name will be::

    ${CPACK_PACKAGE_FILE_NAME}.${CPACK_PACKAGE_CHECKSUM}

  Supported algorithms are those listed by the
  :ref:`string(\<HASH\>) <Supported Hash Algorithms>` command.

.. variable:: CPACK_PROJECT_CONFIG_FILE

  CPack-time project CPack configuration file.  This file is included at cpack
  time, once per generator after CPack has set :variable:`CPACK_GENERATOR`
  to the actual generator being used.  It allows per-generator setting of
  ``CPACK_*`` variables at cpack time.

.. variable:: CPACK_RESOURCE_FILE_LICENSE

  License to be embedded in the installer.  It will typically be displayed
  to the user by the produced installer (often with an explicit "Accept"
  button, for graphical installers) prior to installation.  This license
  file is NOT added to the installed files but is used by some CPack generators
  like NSIS.  If you want to install a license file (may be the same as this
  one) along with your project, you must add an appropriate CMake
  :command:`install` command in your ``CMakeLists.txt``.

.. variable:: CPACK_RESOURCE_FILE_README

  ReadMe file to be embedded in the installer.  It typically describes in
  some detail the purpose of the project during the installation.  Not all
  CPack generators use this file.

.. variable:: CPACK_RESOURCE_FILE_WELCOME

  Welcome file to be embedded in the installer.  It welcomes users to this
  installer.  Typically used in the graphical installers on Windows and Mac
  OS X.

.. variable:: CPACK_MONOLITHIC_INSTALL

  Disables the component-based installation mechanism.  When set, the
  component specification is ignored and all installed items are put in a
  single "MONOLITHIC" package.  Some CPack generators do monolithic
  packaging by default and may be asked to do component packaging by
  setting ``CPACK_<GENNAME>_COMPONENT_INSTALL`` to ``TRUE``.

.. variable:: CPACK_GENERATOR

  List of CPack generators to use.  If not specified, CPack will create a
  set of options following the naming pattern
  :variable:`CPACK_BINARY_<GENNAME>` (e.g. ``CPACK_BINARY_NSIS``) allowing
  the user to enable/disable individual generators.  If the ``-G`` option is
  given on the :manual:`cpack <cpack(1)>` command line, it will override this
  variable and any ``CPACK_BINARY_<GENNAME>`` options.

.. variable:: CPACK_OUTPUT_CONFIG_FILE

  The name of the CPack binary configuration file.  This file is the CPack
  configuration generated by the CPack module for binary installers.
  Defaults to ``CPackConfig.cmake``.

.. variable:: CPACK_PACKAGE_EXECUTABLES

  Lists each of the executables and associated text label to be used to
  create Start Menu shortcuts.  For example, setting this to the list
  ``ccmake;CMake`` will create a shortcut named "CMake" that will execute the
  installed executable ``ccmake``.  Not all CPack generators use it (at least
  NSIS, WIX and OSXX11 do).

.. variable:: CPACK_STRIP_FILES

  List of files to be stripped.  Starting with CMake 2.6.0,
  ``CPACK_STRIP_FILES`` will be a boolean variable which enables
  stripping of all files (a list of files evaluates to ``TRUE`` in CMake,
  so this change is compatible).

.. variable:: CPACK_VERBATIM_VARIABLES

  .. versionadded:: 3.4

  If set to ``TRUE``, values of variables prefixed with ``CPACK_`` will be
  escaped before being written to the configuration files, so that the cpack
  program receives them exactly as they were specified.  If not, characters
  like quotes and backslashes can cause parsing errors or alter the value
  received by the cpack program.  Defaults to ``FALSE`` for backwards
  compatibility.

.. variable:: CPACK_THREADS

  .. versionadded:: 3.20

  Number of threads to use when performing parallelized operations, such
  as compressing the installer package.

  Some compression methods used by CPack generators such as Debian or Archive
  may take advantage of multiple CPU cores to speed up compression.
  ``CPACK_THREADS`` can be set to positive integer to specify how many threads
  will be used for compression. If it is set to 0, CPack will set it so that
  all available CPU cores are used.
  By default ``CPACK_THREADS`` is set to ``1``.

  Currently only ``xz`` compression *may* take advantage of multiple cores. Other
  compression methods ignore this value and use only one thread.

  .. note::

     Official CMake binaries available on ``cmake.org`` ship with a ``liblzma``
     that does not support parallel compression.

Variables for Source Package Generators
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

The following CPack variables are specific to source packages, and
will not affect binary packages:

.. variable:: CPACK_SOURCE_PACKAGE_FILE_NAME

  The name of the source package.  For example ``cmake-2.6.1``.

.. variable:: CPACK_SOURCE_STRIP_FILES

  List of files in the source tree that will be stripped.  Starting with
  CMake 2.6.0, ``CPACK_SOURCE_STRIP_FILES`` will be a boolean
  variable which enables stripping of all files (a list of files evaluates
  to ``TRUE`` in CMake, so this change is compatible).

.. variable:: CPACK_SOURCE_GENERATOR

  List of generators used for the source packages.  As with
  :variable:`CPACK_GENERATOR`, if this is not specified then CPack will
  create a set of options (e.g. ``CPACK_SOURCE_ZIP``) allowing
  users to select which packages will be generated.

.. variable:: CPACK_SOURCE_OUTPUT_CONFIG_FILE

  The name of the CPack source configuration file.  This file is the CPack
  configuration generated by the CPack module for source installers.
  Defaults to ``CPackSourceConfig.cmake``.

.. variable:: CPACK_SOURCE_IGNORE_FILES

  Pattern of files in the source tree that won't be packaged when building
  a source package.  This is a list of regular expression patterns (that
  must be properly escaped), e.g.,
  ``/CVS/;/\\.svn/;\\.swp$;\\.#;/#;.*~;cscope.*``

Variables for Advanced Use
^^^^^^^^^^^^^^^^^^^^^^^^^^

The following variables are for advanced uses of CPack:

.. variable:: CPACK_CMAKE_GENERATOR

  What CMake generator should be used if the project is a CMake
  project.  Defaults to the value of :variable:`CMAKE_GENERATOR`.  Few users
  will want to change this setting.

.. variable:: CPACK_INSTALL_CMAKE_PROJECTS

  List of four values that specify what project to install.  The four values
  are: Build directory, Project Name, Project Component, Directory.  If
  omitted, CPack will build an installer that installs everything.

.. variable:: CPACK_SYSTEM_NAME

  System name, defaults to the value of :variable:`CMAKE_SYSTEM_NAME`,
  except on Windows where it will be ``win32`` or ``win64``.

.. variable:: CPACK_PACKAGE_VERSION

  Package full version, used internally.  By default, this is built from
  :variable:`CPACK_PACKAGE_VERSION_MAJOR`,
  :variable:`CPACK_PACKAGE_VERSION_MINOR`, and
  :variable:`CPACK_PACKAGE_VERSION_PATCH`.

.. variable:: CPACK_TOPLEVEL_TAG

  Directory for the installed files.

.. variable:: CPACK_INSTALL_COMMANDS

  Extra commands to install components.  The environment variable
  ``CMAKE_INSTALL_PREFIX`` is set to the temporary install directory
  during execution.

.. variable:: CPACK_INSTALL_SCRIPTS

  .. versionadded:: 3.16

  Extra CMake scripts executed by CPack during its local staging
  installation.  They are executed before installing the files to be packaged.
  The scripts are not called by a standalone install (e.g.: ``make install``).
  For every script, the following variables will be set:
  :variable:`CMAKE_CURRENT_SOURCE_DIR`, :variable:`CMAKE_CURRENT_BINARY_DIR`
  and :variable:`CMAKE_INSTALL_PREFIX` (which is set to the staging install
  directory).  The singular form ``CMAKE_INSTALL_SCRIPT`` is supported as
  an alternative variable for historical reasons, but its value is ignored if
  ``CMAKE_INSTALL_SCRIPTS`` is set and a warning will be issued.

  See also :variable:`CPACK_PRE_BUILD_SCRIPTS` and
  :variable:`CPACK_POST_BUILD_SCRIPTS` which can be used to specify scripts
  to be executed later in the packaging process.

.. variable:: CPACK_PRE_BUILD_SCRIPTS

  .. versionadded:: 3.19

  List of CMake scripts to execute after CPack has installed the files to
  be packaged into a staging directory and before producing the package(s)
  from those files. See also :variable:`CPACK_INSTALL_SCRIPTS` and
  :variable:`CPACK_POST_BUILD_SCRIPTS`.

.. variable:: CPACK_POST_BUILD_SCRIPTS

  .. versionadded:: 3.19

  List of CMake scripts to execute after CPack has produced the resultant
  packages and before copying them back to the build directory.
  See also :variable:`CPACK_INSTALL_SCRIPTS`,
  :variable:`CPACK_PRE_BUILD_SCRIPTS` and :variable:`CPACK_PACKAGE_FILES`.

.. variable:: CPACK_PACKAGE_FILES

  .. versionadded:: 3.19

  List of package files created in the staging directory, with each file
  provided as a full absolute path.  This variable is populated by CPack
  just before invoking the post-build scripts listed in
  :variable:`CPACK_POST_BUILD_SCRIPTS`.  It is the preferred way for the
  post-build scripts to know the set of package files to operate on.
  Projects should not try to set this variable themselves.

.. variable:: CPACK_INSTALLED_DIRECTORIES

  Extra directories to install.

.. variable:: CPACK_PACKAGE_INSTALL_REGISTRY_KEY

  Registry key used when installing this project.  This is only used by
  installers for Windows.  The default value is based on the installation
  directory.

.. variable:: CPACK_CREATE_DESKTOP_LINKS

  List of desktop links to create.  Each desktop link requires a
  corresponding start menu shortcut as created by
  :variable:`CPACK_PACKAGE_EXECUTABLES`.

.. variable:: CPACK_BINARY_<GENNAME>

  CPack generated options for binary generators.  The ``CPack.cmake`` module
  generates (when :variable:`CPACK_GENERATOR` is not set) a set of CMake
  options (see CMake :command:`option` command) which may then be used to
  select the CPack generator(s) to be used when building the ``package``
  target or when running :manual:`cpack <cpack(1)>` without the ``-G`` option.
