CPack Archive Generator
-----------------------
CPack generator for packaging files into an archive, which can have
any of the following formats:
- 7Z - 7zip - (.7z)
- TBZ2 (.tar.bz2)
- TGZ (.tar.gz)
- TXZ (.tar.xz)
- TZ (.tar.Z)
- TZST (.tar.zst)
- ZIP (.zip)
.. versionadded:: 3.1
``7Z`` and ``TXZ`` formats support.
.. versionadded:: 3.16
``TZST`` format support.
When this generator is called from ``CPackSourceConfig.cmake`` (or through
the ``package_source`` target), then the generated archive will contain all
files in the project directory, except those specified in
:variable:`CPACK_SOURCE_IGNORE_FILES`. The following is one example of
packaging all source files of a project:
.. code-block:: cmake
set(CPACK_SOURCE_GENERATOR "TGZ")
set(CPACK_SOURCE_IGNORE_FILES
\\.git/
build/
".*~$"
)
set(CPACK_VERBATIM_VARIABLES YES)
include(CPack)
When this generator is called from ``CPackConfig.cmake`` (or through the
``package`` target), then the generated archive 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`).
Variables specific to CPack Archive generator
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
.. variable:: CPACK_ARCHIVE_FILE_NAME
CPACK_ARCHIVE_<component>_FILE_NAME
Package file name without extension. The extension is determined from the
archive format (see list above) and automatically appended to the file name.
The default is ``<CPACK_PACKAGE_FILE_NAME>[-<component>]``, with spaces
replaced by '-'.
.. versionadded:: 3.9
Per-component ``CPACK_ARCHIVE_<component>_FILE_NAME`` variables.
.. variable:: CPACK_ARCHIVE_COMPONENT_INSTALL
Enable component packaging. If enabled (ON), then the archive generator
creates multiple packages. The default is OFF, which means that a single
package containing files of all components is generated.
Variables used by CPack Archive generator
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
These variables are used by the Archive generator, but are also available to
CPack generators which are essentially archives at their core. These include:
- :cpack_gen:`CPack Cygwin Generator`
- :cpack_gen:`CPack FreeBSD Generator`
.. variable:: CPACK_ARCHIVE_THREADS
.. versionadded:: 3.18
The number of threads to use when performing the compression. If set to
``0``, the number of available cores on the machine will be used instead.
The default is ``1`` which limits compression to a single thread. Note that
not all compression modes support threading in all environments. Currently,
only the XZ compression may support it.
See also the :variable:`CPACK_THREADS` variable.
.. note::
Official CMake binaries available on ``cmake.org`` ship with a ``liblzma``
that does not support parallel compression.
