# CMakeForceCompiler
|
|
# ------------------
|
|
#
|
|
#
|
|
#
|
|
# 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)
|
