Okay on a clean system cmake building from master after building there are
no mythtv python bindings anywhere on the computer.

plocate site-packages grep -i mythtv

produces nothing. If I look at the console of the sudo cmake --build
build-qt5 I see the error:

error: externally-managed-environment

× This environment is externally managed
╰─> To install Python packages system-wide, try 'pacman -S
   python-xyz', where xyz is the package you are trying to
   install.

   If you wish to install a non-Arch-packaged Python package,
   create a virtual environment using 'python -m venv path/to/venv'.
   Then use path/to/venv/bin/python and path/to/venv/bin/pip.

   If you wish to install a non-Arch packaged Python application,
   it may be easiest to use 'pipx install xyz', which will manage a
   virtual environment for you. Make sure you have python-pipx
   installed via pacman.

note: If you believe this is a mistake, please contact your Python
installation or OS distribution provider. You can override this, at the
risk of breaking your Python in
stallation or OS, by passing --break-system-packages.
hint: See PEP 668 for the detailed specification.
