How to include package dependencies that are not available via PyPi?

[laali]

Is there a way to include dependencies that are not published PyPi in a pantsbuid BUILD file? Is there an option like dependency_links in setuptools?

Thanks

One example, which mimics the `--find-links` behavior of pip when pex is doing resolution, from our pants.ini:

```

[python-repos]

repos: [

    '%(buildroot)s/.wheelhouse'

  ]

```

`.wheelhouse` is a directory that our bootstrapping scripts maintain which contains a bunch of (potentially platform specific) wheels that define the universe of third party python dependencies available to pants for resolution.

Laalitha's question is likely in re: https://github.com/pantsbuild/pants/issues/1751

I have a fully worked example of Patrick's reccomendation, although the set of prebuilts is kept minimal to highlight exactly which of Laalitha's deps is broken with respect to naive auto-install  via pip/pex/pants: https://github.com/pantsbuild/issues-1751

The issues here center around numpy-ecosystem distributions which have been problematic to install in my experience over at least the last 4 years if not over their entire history.  Though problematic to install these are highly useful/used libs so hopefully the example repo pulls it's weight over time as an example of what to do if you want to use pants and numpy-foo.
