Boost.Python and setuptools

[edmcman]

I don't think setuptools is a supported method to build Boost.Python projects, and I suspect there will be more trouble with this in the future. Modern versions of Boost.Python include the python version in the name (e.g., boost_python38) and on Windows, we get even more fun names like boost_python38-vc142-mt-gd-x64-1_72.lib.

I think the right thing to do would be to override setuptools to use cmake, or use bjam. Boost kind of sucks.

Here's an example of using cmake: https://gist.github.com/hovren/5b62175731433c741d07ee6f482e2936
