When building Qt with ANGLE, ParaView can't be built

With the current configuration, building ParaView with a built Qt that is using ANGLE is not possible (nor recommended anyway). The folowing error appears :

error C2065: 'GL_RENDERBUFFER_SAMPLES": undeclared identifier

It would be nice to check the OpenGL implementation used by Qt, and also to force the OpenGL implementation to be dynamic with -opengl dynamic flag passed to Qt configuration.

As a side note, due to another bug common-superbuild#45 (closed), ParaView currently cannot be built on windows/vs2015 with a built Qt.
