This is mostly a bug report to document an exiting issue that may not need to be fixed.

The python directory in the source has a setup.py so it should be possible to run pip install . in the directory to install the software. Sadly this is not working if pip version is inferior to 22.x.x. The reason is that pip before that release was running the code in a temporary copy of the python directory. As it is a copy, it can not access to configure.ac in the upper directory.

So a workaround for people that want to use pip install . is to update pip to 22.x.x or above by running pip install --upgrade pip.
