glspectrum / projectm doesn't start on win32

Both visu glspectrum and projectm doesn't run on win32 because vlc_gl_surface_Create can't find a "glx" opengl module. I tried to replace "glx" with "glwin32" or "opengl", but this still doesn't work.

Logs from my app, bug they are the same with vlc :

D visualization - core:  looking for visualization module matching "projectm": 4 candidates
