MinGW Conflicts

The CMakeLists provided in A5 does not play nice with MinGW cross-compiling. It includes the host system's standard library and causes multiple declaration errors:

User error or no?

Probably need to add check the value of CMAKE_CROSSCOMPILING and set include directories according to this value.
I currently don't have enough time to validate this, but you're welcome to open a PR :)
