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. 15
