Impossible to buld with pure OpenGL desktop on Windows: ANGLE always used

I wanted to build Qt from sources using win32-msvc2012, since I don't want to use the default ANGLE opengl backend.

I passed the following during configure:

-no-angle -opengl desktop

But Qt just does not care at all! ANGLE is still built and used ... I also noticed the EGL libs were built (is it normal for regular desktop OpenGL?).

Then I built Qt3D and the small opengl info program clearly shows that it's ANGLE and not my pure NVIDIA OpenGL.

It seems like something in a config file overides my settings, I could not manager to get a build with pure desktop OpenGL.

Any workaround? Can I force not using ANGLE by editing some config file?
