Hi,

if you use Weston, I think you should be able to avoid all of Mesa by
using Weston's Pixman renderer (--use-pixman on the command line).
Weston has build options to not build the GL-renderer that needs GL
drivers (e.g. Mesa). You can disable a lot by Weston's build options to
avoid many dependencies, e.g. everything X11 related.

I recommend using Weston's DRM-backend if possible, but if not,
fbdev-backend still exist for very limited use cases.

We just merged kiosk-shell in Weston, too, which might be interesting
for your single-app use case.

Mind, that for BSD you will still need downstream patches, since
libwayland and weston use some Linuxisms.


Thanks,
pq
