| CMAKE_COMPILER_IS_GNU<LANG> | |
| --------------------------- | |
| True if the compiler is GNU. | |
| If the selected ``<LANG>`` compiler is the GNU compiler then this is ``TRUE``, | |
| if not it is ``FALSE``. Unlike the other per-language variables, this | |
| uses the GNU syntax for identifying languages instead of the CMake | |
| syntax. Recognized values of the ``<LANG>`` suffix are: | |
| :: | |
| CC = C compiler | |
| CXX = C++ compiler | |
| G77 = Fortran compiler |
