Thanks for taking the time to investigate this! It looks like we're
indeed covered as far as Ninja is concerned.

We don't have it enabled, but a while ago we agreed that it's
acceptable to add it to the CentOS guests, so installing Ninja from
EPEL shouldn't be a problem.

I agree that it's almost certainly just a matter of sitting down
and, you know, actually implementing it :) But let me reiterate that
I don't think we should consider releasing a version of libvirt-dbus
that uses Meson for builds until we have proper Meson support in our
CI. Perhaps we're all on the same page already and this wouldn't
even need mentioning, but I'm being extremely clear about my position
just in case.
