I was quite sure that you need your project to use at least one language, but that it does not need to be C/C++.
If you have issues with the internal test then a special TOOLCHAIN file is the way to go. I had to do this for a special fortran compiler that only built 32bit packages on a 64bit system. If memory servers me well you just need to put INCLUDE(CMakeForceCompiler) in your toolchain file.
