Yes, I was planning to reference the work you did in the cover letter for
this patch, but git-send-email is terrible.

I honestly didn't look at your patchset before doing this work — and, to be
fair, I did this over my lunch break, so I didn't really get into doing
anything more than a mechanical port.

I'd be happy to improve the build by merging my approach and yours. My
patch is slightly more idiomatic with regards to recent Meson; it allows
using wayland-protocols as a subproject, as it doesn't use
`meson.source_root()` in paths; and it generates the pkg-config file
directly instead of going through a template file.

I did leave the Autotools build in place because I don't know if people
using wayland-protocols can also rely on having a recent version of Meson
and Python 3.

Ciao,
 Emmanuele.
