[CMake] List of object files

[zia at itsib.ru]

I want swap MSVC linker to my linker(e.g. RTOS), but I don't know as to make this.
And I have an idea.I'll run EXEC_PROGRAM command with parameter. Where I run 
EXEC_PROGRAM("my linker" objparam)

p.s. 
I set CMake variable, but it is not work.
Set(CMAKE_CXX_LINK_EXECUTABLE)
Set(CMAKE_C_LINK_EXECUTABLE)
