That works, at least for the file name. There are some remaining  
problems, though:
That compiler can only handle Windows-like paths (it tries to be smart  
but isn't) and thus only works with the "NMake Makefiles" generator.  
To specify the output _directory_, the option -dir can be used and  
luckily, cmake provides a <OBJECT_DIR>. However, the content of that  
is not a Windows path but a cmake path (containing '/' instead of '\').
Additionally, the compiler test assumes that the compiler creates the  
directory itself (it doesn't) but that can be worked around in  
CMAKE_C_COMPILE_OBJECT. Better would be to not assume that.

It is possible to fix this for CMake-2.6?
