[CMake] Can't build something with MinGW

[Mathieu Bridon]

Hi,

I'm still blocked with this.

I found this, though:

    https://cmake.org/Bug/view.php?id=13855

Using the patch attached to this bug, I'm able to build stuff
correctly.

However, that patch still feels weird to me, because it makes the Linux
-GNU.cmake platform file take into account the fact that I'm using
MinGW.

But should I really need this? It still seems bizarre that the platform
goes from "Windows" to "Linux-GNU" in the middle of my build...

Any idea how to fix this?
