I guess I misunderstood that a bit. ;-) With former you've likely meant

  * it will produce a libGLX_mesa.so

with latter

  * the usual "conflicting" libGLES* and libEGL files

The conflicting libEGL files issue has been addressed by a NVIDIA employee
apparently: Kyle Brenneman <kbrenneman at nvidia.com>

Not upstreamed yet, but received at least a reviewed by

  Adam Jackson <ajax at redhat.com>

in January after after Dylan Baker reviewed the patch already in September

  https://lists.freedesktop.org/archives/mesa-dev/2016-September/128716.html

I've applied both patches and it apparently fixes the libEGL conflict issue
for me. If I understood correctly you planned to add NVIDIA's libglvnd EGL
support to Mesa 17.1 - after polishing it.

So what's missing is GLES support for libglvnd builds in Mesa. At least this
is my understanding with NVIDIA and maybe also other vendors replacing these
libs with theirs.

Adding NVIDIA at this point. Kyle and Daniel. Hope that's ok.

Thanks,
Stefan
