| This file provides a few notes to CMake developers about how to add |
| support for a new language to CMake. It is also possible to place |
| these files in :variable:`CMAKE_MODULE_PATH` within an outside project |
| to add languages not supported by upstream CMake. However, this is not |
| a fully supported use case. |
| |
| The implementation behind the scenes of project/enable_language, |
| including the compiler/platform modules, is an *internal* API that |
| does not make any compatibility guarantees. It is not covered in the |
| official reference documentation that is versioned with the source code. |
| Maintainers of external language support are responsible for porting |
| it to each version of CMake as upstream changes are made. Since |
| the API is internal we will not necessarily include notice of any |
| changes in release notes. |

| CMakeDetermine(LANG)Compiler.cmake -> this should find the compiler for LANG and configure CMake(LANG)Compiler.cmake.in |
| |
| CMake(LANG)Compiler.cmake.in -> used by CMakeDetermine(LANG)Compiler.cmake |
| This file is used to store compiler information and is copied down into try |
| compile directories so that try compiles do not need to re-determine and test the LANG |
| |
| CMakeTest(LANG)Compiler.cmake -> test the compiler and set: |
| SET(CMAKE_(LANG)_COMPILER_WORKS 1 CACHE INTERNAL "") |
| |
| CMake(LANG)Information.cmake -> set up rule variables for LANG : |
| CMAKE_(LANG)_CREATE_SHARED_LIBRARY |
| CMAKE_(LANG)_CREATE_SHARED_MODULE |
| CMAKE_(LANG)_CREATE_STATIC_LIBRARY |
| CMAKE_(LANG)_COMPILE_OBJECT |
| CMAKE_(LANG)_LINK_EXECUTABLE |
