Dave gave some comments some time ago about issues he had with meson (
put him in CC). I'm also contributing to virgl, but this patch I didn't
sign as Collaboran because this is more about my personal opinion that
the removal of autotools without prior deprecation doesn't seem to me
to be a good idea.

I'm happy, btw, that all those in favour of removing autotools sooner
than later went this step in my direction and have acknowledged this
patch (and thanks to all the others too), but I will not push it with
the strong NAK you gave, Ilia. To me consensus means that all who
contribute significantly to the project (like you certainly do) agree
or abstain, but don't object.

Best,
Gert
