It's not wrong, as Qt could be compiled with GL or GLES backend, and
it we can't rely on it to bring the GL headers in both situations.
Also, it doesn't make sense to change the libgles2-mesa-dev package to
depend on libgl1-mesa-dev, as it's not needed. And we can also have
the case where you want to build using some vendor's GLES drivers,
that provides libgles2-dev (libqt4-opengl-dev depends on
libgles2-mesa-dev | libgles2-dev).
After looking again it seems for me that upstream is just wrong
assuming Qt will have OpenGL support if it can find gl.h in the
system. It seems that it should just rely on
HAS_QT_MODULE(QT_QTOPENGL_FOUND QtOpenGL), or at least check both gl.h
and egl.h if it's really needed.
Will discuss with upstream to see what is the preferred fix, meanwhile
we can remove the mesa relation with this bug.
