Title: setup.py: `--use-system-sofa` missing

The option to use a system provided SOFA library is missing in
```
python setup.py build --help
```
Debian and Ubuntu provide them as separate packages, so it may be worth to allow their usage.
Is an external SOFA library used with the `--use-system-libraries` flag?
