# 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.
|
|
#
|
|
# 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)
