| <p>This internally calls the check_fortran_source_compiles macro and |
| sets CMAKE_REQUIRED_DEFINITIONS to <flag>. See help for |
| CheckFortranSourceCompiles for a listing of variables that can |
| otherwise modify the build. The result only tells that the compiler |
| does not give an error message when it encounters the flag. If the |
| flag has any effect or even a specific one is beyond the scope of |
| this module.</p> |
