| use_mangled_mesa(PATH_TO_MESA OUTPUT_DIRECTORY) | |
| The path to mesa includes, should contain ``gl_mangle.h``. The mesa | |
| headers are copied to the specified output directory. This allows | |
| mangled mesa headers to override other GL headers by being added to | |
| the include directory path earlier. |
