Well, [1] is about adding QT_EGL_NO_X11, which is a QT definition. It
is very different from MESA_EGL_NO_X11_HEADERS, which is an
OpenGL-level definition.

I'm not sure I fully understand those patches, but apparently they use
more pkg-config flags from OpenGL, which is exactly the approach I
suggest to investigate indeed.

BTW, the same thing should be done for Qt instead of
package/qt/0012-OpenGL-EGL-Avoid-X11-header-collision.patch.

Best regards,

Thomas
