An alternative idea, meson 0.54.0 depends on Python 3.8 ABI. Python 3.8 is
available on CentOS-8, so maybe we could try asking for a meson 0.54 build on
CentOS 8 as well.
CentOS 7 would be great too, but I'm willing to accept a compromise here that
we will only do an RPM build on the latest CentOS. I mean, compiling the code
on CentOS 7 is one thing, but building an RPM brings its own
issues/dependencies (a similar problem can be observed with libvirt-tck where
CentOS 7 simply turned out to be an unsuitable platform), from upstream POV we
mainly care about the latest releases of our dependencies for any *reasonable*
development anyway, so shifting the focus slightly to the latest CentOS in
terms of doing an RPM build doesn't seem like such an issue to me - all of
^this assuming we could get a newer meson build.
