| # ------------------ |
| # |
| # |
| # |
| # This module defines macros intended for use by cross-compiling |
| # toolchain files when CMake is not able to automatically detect the |
| # compiler identification. |
| # |
| # Macro CMAKE_FORCE_C_COMPILER has the following signature: |
| # |
| # :: |
| # |
| # CMAKE_FORCE_C_COMPILER(<compiler> <compiler-id>) |
| # |
| # It sets CMAKE_C_COMPILER to the given compiler and the cmake internal |
| # variable CMAKE_C_COMPILER_ID to the given compiler-id. It also |
| # bypasses the check for working compiler and basic compiler information |
| # tests. |
| # |
| # Macro CMAKE_FORCE_CXX_COMPILER has the following signature: |
| # |
| # :: |
| # |
| # CMAKE_FORCE_CXX_COMPILER(<compiler> <compiler-id>) |
| # |
| # It sets CMAKE_CXX_COMPILER to the given compiler and the cmake |
| # internal variable CMAKE_CXX_COMPILER_ID to the given compiler-id. It |
| # also bypasses the check for working compiler and basic compiler |
| # information tests. |
| # |
| # Macro CMAKE_FORCE_Fortran_COMPILER has the following signature: |
| # |
| # :: |
| # |
| # CMAKE_FORCE_Fortran_COMPILER(<compiler> <compiler-id>) |
| # |
| # It sets CMAKE_Fortran_COMPILER to the given compiler and the cmake |
| # internal variable CMAKE_Fortran_COMPILER_ID to the given compiler-id. |
| # It also bypasses the check for working compiler and basic compiler |
| # information tests. |
| # |
| # So a simple toolchain file could look like this: |
| # |
| # :: |
| # |
| # include (CMakeForceCompiler) |
| # set(CMAKE_SYSTEM_NAME Generic) |
| # CMAKE_FORCE_C_COMPILER (chc12 MetrowerksHicross) |
| # CMAKE_FORCE_CXX_COMPILER (chc12 MetrowerksHicross) |
