Use site.cfg.example as template to create a new site.cfg. For openblas, uncomment: [openblas] library_dirs = /opt/OpenBLAS/lib include_dirs = /opt/OpenBLAS/include Also, uncomment default section: [DEFAULT] library_dirs = /usr/local/lib include_dirs = /usr/local/include That should do it - hopefully.

I did get this figured out (wanted to try out openblas), but it could be a small barrier to new users.
That should be explained in INSTALL.txt. It may be a bit outdated at this point. If so, could you make a PR adding relevant bits from your experience.
