Ok, so it is definitely cross compiling.
In the sense that CMAKE_CROSSCOMPILING needs to be set (which indicates e.g. 
to TRY_RUN() that it cannot run the executables).

What's the operating system on the XBox ?

Did they really create an OS additional to the x86 Windows (NT), Win CE and 
Windows Mobile ? I would guess it is based on Win CE ?
Or is it really basically Win (NT) ? :

In which way do you think doesn't it match the cross compiling philosopy of 
cmake ?

Windows-cl.cmake needs to be refactored in order to support cross compiling, 
XBox, Win CE etc. It will look different afterwards.

I would assume it is :-)
