CheckLanguage
Check if a language can be enabled
Usage:
check_language(<lang>)
where <lang>
is a language that may be passed to enable_language() such as Fortran
. If CMAKE__COMPILER is already defined the check does nothing. Otherwise it tries enabling the language in a test project. The result is cached in CMAKE__COMPILER as the compiler that was found, or NOTFOUND
if the language cannot be enabled. For CUDA which can have an explicit host compiler, the cache CMAKE_CUDA_HOST_COMPILER variable will be set if it was required for compilation (and cleared if it was not).
Example:
check_language(Fortran) if(CMAKE_Fortran_COMPILER) enable_language(Fortran) else() message(STATUS "No Fortran support") endif()
