+On Debian `PYTHON_SETUP_ARGS=--install-layout=deb` needs to be set when installing the python wrappers in order to create the correct python directory structure.
 
 To run tests with the built libraries and programs, several paths (relative to `$DESTDIR`) need to be added to variables `$LD_LIBRARY_PATH`, `$PATH` and `$PYTHONPATH`.
 This can be done using [./scripts/env_use_destdir](./scripts/env_use_destdir):
