[Cmake] gtk-config..again

[Mathieu Malaterre]

Ok sorry,
	I was a bit too quick. So this time for real,
	I would like to know why you didn't used the gtk-config script for 
Module/FindGTK.cmake

---
And in FindwxWindows (not FindGTK) could you change:

   SET(WXWINDOWS_LIBRARY "`${CMAKE_WX_CONFIG} --libs`")

into

   SET(WXWINDOWS_LIBRARY "`${CMAKE_WX_CONFIG} --libs --gl-libs`")

thanks,
mathieu
