As a comparison, on an Archlinux VM I used the ansible dependencies for
mythtv and then git cloned the AUR mythtv-git.

I modified only the fixes/35 from 34 in the PKGBUILD file, and then built
the package with makepkg -si

Once it complete I did the sudo updatedb, plocate site-packages | grep -i
mythtv and this time I got a bunch of files.

So I have not built a full mythtv combo BE/FE but this answers part of the
question.

Something is different between the new cmake build and the old ./configure,
make, sudo make install that is keeping the python bindings from being
built for Archlinux.
