Please have a look at the attached file and put it into your cmake/Modules/
directory and let me know what you think.
It includes three simple macros, with these you can change your toolchain file
to:
include(CMakeForceCompiler)
# force system name, version and processor
cmake_force_system("Generic" "1.0" "hc12")
# this one sets the compiler to "chc12", the sizeof(void) to 2
# and the "compiler id" to "FreescaleCHC12".
# With a compiler id cmake will try to load
# ${CMAKE_SYSTEM_NAME}-${ID}-C.cmake for C and
# ${CMAKE_SYSTEM_NAME}-${ID}-CXX.cmake for C++
cmake_force_c_compiler(chc12 FreescaleCHC12 2)
# same for C++, the size is not needed here
cmake_force_cxx_compiler(chc12 FreescaleCHC12)
-------------------------------------------------------------
Can't you move the following three also in the toolchain file ?
If they are already in the cache, you could try the FORCE option.
SET (HC12_PIPER "piper" CACHE STRING "Freescale tool...")
SET (CMAKE_AR "libmaker" CACHE STRING "Tool chain library archiver")
SET (CMAKE_LINKER "linker" CACHE STRING "Tool chain linker")
