OK, I created a branch at:
lp:~guillaume-chereau/stellarium/qt-5-3-windows-opengl
This is not as simple as I thought: instead of using the GL macro I
actually redefine (through a macro) all the Opengl ES 2 calls to use the
current context QOpenGLFunctions object.
The nice thing is that it is totally transparent, the ugly thing is
that it makes a lot of macros in StelOpenGL.hpp
I could compile with Qt 5.3 Opengl on Windows, though I had a few
problems with the recent changes to the CMakeList.txt file. I think it
should also work with Qt 5.2.
I also noticed a bug in the rendering of the sun on this branch, but
this is maybe due to some unrelated issue.
Regards,
Guillaume
