enable_language(<lang> [OPTIONAL] )
|
|
|
|
|
|
|
|
|
|
This command enables support for the named language in CMake. This is
|
|
|
|
|
the same as the project command but does not create any of the extra
|
|
|
|
|
variables that are created by the project command. Example languages
|
|
|
|
|
are ``CXX``, ``C``, ``CUDA``, ``Fortran``, and ``ASM``.
|
|
|
|
|
|
|
|
|
|
If enabling ``ASM``, enable it last so that CMake can check whether
|
|
|
|
|
compilers for other languages like ``C`` work for assembly too.
|
|
|
|
|
|
|
|
|
|
This command must be called in file scope, not in a function call.
|
|
|
|
|
Furthermore, it must be called in the highest directory common to all
|
|
|
|
|
targets using the named language directly for compiling sources or
|
|
|
|
|
indirectly through link dependencies. It is simplest to enable all
|
|
|
|
|
needed languages in the top-level directory of a project.
|
|
|
|
|
|
|
|
|
|
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.
