MESSAGE(FATAL_ERROR
"Do not include the CMakeForceCompiler module. "
"It is no longer necessary. "
"Update your toolchain file as follows.
# 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 ???
#
# 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 ???
#
# 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)
Use of the CMAKE_FORCE_SYSTEM macro:
MACRO(CMAKE_FORCE_C_COMPILER compiler id)
SET(CMAKE_C_COMPILER "${compiler}")
SET(CMAKE_C_COMPILER_ID_RUN TRUE)
SET(CMAKE_C_COMPILER_ID ${id})
SET(CMAKE_C_COMPILER_WORKS TRUE)
SET(CMAKE_C_COMPILER_FORCED TRUE)
CMAKE_FORCE_SYSTEM(\"<name>\" \"<version>\" \"<processor>\")
# Set old compiler id variables.
IF("${CMAKE_C_COMPILER_ID}" MATCHES "GNU")
SET(CMAKE_COMPILER_IS_GNUCC 1)
ENDIF("${CMAKE_C_COMPILER_ID}" MATCHES "GNU")
ENDMACRO(CMAKE_FORCE_C_COMPILER)
may be replaced by just
MACRO(CMAKE_FORCE_CXX_COMPILER compiler id)
SET(CMAKE_CXX_COMPILER "${compiler}")
SET(CMAKE_CXX_COMPILER_ID_RUN TRUE)
SET(CMAKE_CXX_COMPILER_ID ${id})
SET(CMAKE_CXX_COMPILER_WORKS TRUE)
SET(CMAKE_CXX_COMPILER_FORCED TRUE)
SET(CMAKE_SYSTEM_NAME \"<name>\")
SET(CMAKE_SYSTEM_VERSION \"<version>\")
SET(CMAKE_SYSTEM_PROCESSOR \"<processor>\")
Use of the CMAKE_FORCE_C_COMPILER and CMAKE_FORCE_CXX_COMPILER macros:
CMAKE_FORCE_C_COMPILER (/path/to/cc <id> <sizeof_void_p>)
CMAKE_FORCE_CXX_COMPILER (/path/to/CC <id>)
may be replaced by just
SET(CMAKE_C_COMPILER /path/to/cc)
SET(CMAKE_CXX_COMPILER /path/to/CC)
CMake will automatically detect known compiler IDs and sizeof(void*).

# Set old compiler id variables.
IF("${CMAKE_CXX_COMPILER_ID}" MATCHES "GNU")
SET(CMAKE_COMPILER_IS_GNUCXX 1)
ENDIF("${CMAKE_CXX_COMPILER_ID}" MATCHES "GNU")
ENDMACRO(CMAKE_FORCE_CXX_COMPILER)
