[CMake] Cross compile to platform with two stage compiler.

[Eric LaFranchi]

Yes. The cross compiler is run on Windows and we are setup to use either Windows Command Prompt or Cygwin shell.
What arguments will be passed into the script that is set using the CMAKE_FORCE_C_COMPIELR macro? I assume this is going to be "compiler flags", "source file", and "target file"?
The compiler is not known to CMake and I assume that I will need to create a "Compiler"-C.cmake and put it in my local cmake modules path?
Thanks, Eric

Currently we have 16 different platform that we target that are a combination of native compiles and cross compiles. I am adding a new platform to our build system using CMake's cross compiling facility. This platform is unique in that compiling a ".c" file to get an ".o" file required two steps. These steps: compile the source ".c" to generate a ".asm" file, then assemble that file to get the ".o" file.
For other cross compiled platforms I use CMAKE_FORCE_C_COMPILER, however I am not able to specify both the C compiler and assembler using this macro (my understanding is one compiler as the first argument). I have thought about using ADD_CUSTOM_COMMAND, however I don't want to write a custom command for several thousand C source files.
New ideas are greatly appreciated.

Could the compiler be a script that calls the actual compiler + assembler?
