Subject: [PATCH] build: glx: Lower gl version to work with libglvnd
When using mesa with libglvnd support, mesa will no longer install the
gl, glx, egl pkg-config files but instead let libglvnd provide them.
libglvnd maintainers decided to change the versioning as it was
mesa-specific previously. Now the libraries have versions of the API
they expose[1].
This causes problems when building the X server:
checking for glproto >= 1.4.17 gl >= 9.2.0... no
configure: error: Package requirements (glproto >= 1.4.17 gl >= 9.2.0) were not met:
Requested 'gl >= 9.2.0' but version of gl is 1.2
Lower the version requirement to 1.2 to allow building against libglvnd
provided libraries
