OpenGL from MinGW

[kegon]

I'm trying to build my Linux application under Qt/MinGW and the problem I've hit is OpenGL. I'm using shaders and Windows doesn't ship with a modern OpenGL driver: glext.h is not available and there are no GLSL functions.

I prefer to use Qt binary releases but the mingw version is built with OpenGL, right ?
I would be open to using the ANGLE version if it were available.

What are my options here, because naturally I'm looking for the lazy way ;)

Do I have to build Qt myself with ANGLE ?
Will Qt 5.3 have a mingw/ANGLE binary release ?
Is there a way to use OpenGL 2 on Windows with mingw ?
Any other options ?

Thanks in advance.
