# 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)
