Bug#876100: libglvnd-dev: libglvnd-dev not coinstallable with nvidia packages

[Jiri Palecek <jpalecek@web.de>]

Package: libglvnd-dev
Severity: normal

Dear Maintainer,

libglvnd depends on many OpenGL related packages like libgl1, specified
by concrete version. This means those dependencies can't be satisfied
with virtual packages, ie. nvidia packages providing libgl1. However,
those nvidia packages conflict with any other packages providing those
names, particularly libgl1 et al. provided by libglvnd.

In effect, this makes development packages like
 - libegl1-mesa-dev
 - libsdl2-dev
 - qtbase5-dev
uninstallable on systems with nvidia packages installed. This
restriction didn't exist with mesa packages older than 17.2.0.

Please check if that conflict can be rectified, either on the
libglvnd-dev side, or the nvidia packages (CC-d).

Regards
    Jiri Palecek
