[CMake] Cross-compiling a static library (CMake 2.8.3)

I haven't used that one before. The docs say it should be used
when CMake is not able to detect the compiler ID. Is that the case here?
Have you tried "set(CMAKE_C_COMPILER arm-linux-gcc)"?

The docs say that the signature is
CMAKE_FORCE_C_COMPILER(<compiler> <compiler-id>)
so maybe something bad happens when you give it that extra
argument "4"? Try without "4"?

Best regards,
