I went back and delete build-qt5 directory and rebuilt but with both
options:

sudo cmake --preset qt5 -DMYTH_BINDINGS_INSTALL_ROOT=/
-DCMAKE_INSTALL_PREFIX=/usr
sudo cmake --build build-qt5

This time plocate site-packages | grep -i mythtv  produces a lot of output.

But it also shows this instead of the last PEP668 error. This time it's a
warning.


WARNING: Running pip as the 'root' user can result in broken permissions
and conflicting behaviour with the system package manager, possibly
rendering your system unusabl
e. It is recommended to use a virtual environment instead:
https://pip.pypa.io/warnings/venv. Use the --root-user-action option if you
know what you are doing and want to
suppress this warning.
