[CMake] Setting up mingw toolchain for crosscompiling from Linux

[Nathan Huesken]

Hi,

I removed CMakeChache.txt, I also removed the CMakeFiles folder.
Still does not use the correct  gcc.
It is like it would ignore the DCMAKE_TOOLCHAIN_FILE parameter.

I want to use cmake for a project which should run under linux and windows.
Let's see how it goes :).

Greetings,
Nathan
