Don't worry, it's not really well documented. Create a file called site.cfg in
the root source directory. There's an example site.cfg.example there.
Unfortunately, it's pretty sparse at the moment. Now, I'm not terribly familiar
with the MKL, so I don't know what libraries do what, but here is my guess at
the appropriate things you will need in site.cfg:




There's some more documentation in numpy/distutils/system_info.py .
