-------
|
|
|
|
Set a name, version, and enable languages for the entire project.
|
|
|
|
.. code-block:: cmake
|
|
|
|
project(<PROJECT-NAME> [LANGUAGES] [<language-name>...])
|
|
project(<PROJECT-NAME>
|
|
[VERSION <major>[.<minor>[.<patch>[.<tweak>]]]]
|
|
[LANGUAGES <language-name>...])
|
|
|
|
Sets the name of the project and stores the name in the
|
|
:variable:`PROJECT_NAME` variable. Additionally this sets variables
|
|
|
|
* :variable:`PROJECT_SOURCE_DIR`,
|
|
:variable:`<PROJECT-NAME>_SOURCE_DIR`
|
|
* :variable:`PROJECT_BINARY_DIR`,
|
|
:variable:`<PROJECT-NAME>_BINARY_DIR`
|
|
|
|
If ``VERSION`` is specified, given components must be non-negative integers.
|
|
If ``VERSION`` is not specified, the default version is the empty string.
|
|
The ``VERSION`` option may not be used unless policy :policy:`CMP0048` is
|
|
set to ``NEW``.
|
|
|
|
The :command:`project()` command stores the version number and its components
|
|
in variables
|
|
|
|
* :variable:`PROJECT_VERSION`,
|
|
:variable:`<PROJECT-NAME>_VERSION`
|
|
* :variable:`PROJECT_VERSION_MAJOR`,
|
|
:variable:`<PROJECT-NAME>_VERSION_MAJOR`
|
|
* :variable:`PROJECT_VERSION_MINOR`,
|
|
:variable:`<PROJECT-NAME>_VERSION_MINOR`
|
|
* :variable:`PROJECT_VERSION_PATCH`,
|
|
:variable:`<PROJECT-NAME>_VERSION_PATCH`
|
|
* :variable:`PROJECT_VERSION_TWEAK`,
|
|
:variable:`<PROJECT-NAME>_VERSION_TWEAK`
|
|
|
|
Variables corresponding to unspecified versions are set to the empty string
|
|
(if policy :policy:`CMP0048` is set to ``NEW``).
|
|
|
|
Optionally you can specify which languages your project supports.
|
|
Example languages are ``C``, ``CXX`` (i.e. C++), ``Fortran``, etc.
|
|
By default ``C`` and ``CXX`` are enabled if no language options are
|
|
given. Specify language ``NONE``, or use the ``LANGUAGES`` keyword
|
|
and list no languages, to skip enabling any languages.
|
|
|
|
If a variable exists called :variable:`CMAKE_PROJECT_<PROJECT-NAME>_INCLUDE`,
|
|
the file pointed to by that variable will be included as the last step of the
|
|
project command.
|
|
|
|
The top-level ``CMakeLists.txt`` file for a project must contain a
|
|
literal, direct call to the :command:`project` command; loading one
|
|
through the :command:`include` command is not sufficient. If no such
|
|
call exists CMake will implicitly add one to the top that enables the
|
|
default languages (``C`` and ``CXX``).
|
|
|
|
.. note::
|
|
Call the :command:`cmake_minimum_required` command at the beginning
|
|
of the top-level ``CMakeLists.txt`` file even before calling the
|
|
``project()`` command. It is important to establish version and
|
|
policy settings before invoking other commands whose behavior they
|
|
may affect. See also policy :policy:`CMP0000`.
