1CMAKE_<LANG>_IMPLICIT_INCLUDE_DIRECTORIES
2-----------------------------------------
3
4Directories implicitly searched by the compiler for header files.
5
6CMake does not explicitly specify these directories on compiler
7command lines for language ``<LANG>``.  This prevents system include
8directories from being treated as user include directories on some
9compilers, which is important for ``C``, ``CXX``, and ``CUDA`` to
10avoid overriding standard library headers.
11
12This value is not used for ``Fortran`` because it has no standard
13library headers and some compilers do not search their implicit
14include directories for module ``.mod`` files.
