| enable_language |
| --------------- |
| |
| Enable languages (CXX/C/OBJC/OBJCXX/Fortran/etc) |
| |
| .. code-block:: cmake |
| |
| enable_language(<lang>... [OPTIONAL]) |
| |
| Enables support for the named languages in CMake. This is the same as |
| the :command:`project` command but does not create any of the extra |
| variables that are created by the :command:`project` command. |
| |
| .. include:: include/SUPPORTED_LANGUAGES.rst |
| |
| The following restrictions apply to where ``enable_language()`` may be called: |
| |
| * It must not be called before the first call to :command:`project`. |
| See policy :policy:`CMP0165`. |
| * It must be called such that the command executes before any targets that |
| use the language directly for compiling sources or indirectly through link |
| dependencies. |
| |
| .. note:: |
| Further restrictions apply if policy :policy:`CMP0220` is not set |
| to ``NEW``. See the policy documentation for details. |
| |
| The ``OPTIONAL`` keyword is a placeholder for future implementation and |
| does not currently work. Instead you can use the :module:`CheckLanguage` |
| module to verify support before enabling. |
