| CMAKE_<LANG>_IMPLICIT_INCLUDE_DIRECTORIES |
| ----------------------------------------- |
| |
| Directories implicitly searched by the compiler for header files. |
| |
| CMake does not explicitly specify these directories on compiler |
| command lines for language ``<LANG>``. This prevents system include |
| directories from being treated as user include directories on some |
| compilers, which is important for ``C``, ``CXX``, and ``CUDA`` to |
| avoid overriding standard library headers. |
| |
| This value is not used for ``Fortran`` because it has no standard |
| library headers and some compilers do not search their implicit |
| include directories for module ``.mod`` files. |
