Run Cython tests for binary wheels

[skirpichev]

Closes #447

[skirpichev]

This is an incomplete version so far: MacOS wheels aren't tested yet. Also, probably we should document how users can use bundled libraries for their extensions.

Am I inadvertently blocking progress on this PR?

Am I inadvertently blocking progress on this PR?

No, that's entirely my fault. Some further progress is in test-wheels-cython2 branch.

I'll try to finish this pr today, sorry for a delay.

[skirpichev]

Ok, now it works on MacOS too.

[casevh]

Looks fine. I'll merge the PR and then test with my Windows build process.

[skirpichev]

Hmm, this was a draft. This I think that related issue isn't solved: at least this pr lacks documentation.
