Ah yes, I tested this shim while activating a venv with the extension
installed using `pip -e .`.

It is possible to run this without installing, but it does need a build
step since cffi (in the mode used - which is the recommended mode) needs
to build an extension module.  I did something like this, using my
debian testing system-installed python

$ export PYTHONPATH=$(pwd)/bindings/python-cffi
$ pushd bindings/python-cffi
$ python3 notdb/_build.py  # creates notdb/_capi.cpython-37m-x86_64-linux-gnu.so
$ popd
$ pushd test
$ ./T391-pytest.sh

Does that more or less work?  One problem with this is that it will pick
up the system-wide installed notmuch though.  I guess the way to change
this is by tweaking CFLAGS=-I... LDFLAGS=-L... or so when building?  But
than you also have the whole RPATH/LD_LIBRARY_PATH stuff going on as
well.  Does notmuch abstract any of this away already for it's test
suite?

Cheers,
Floris
