pyproj 3.0.0 uses cython on install but doesn't list it as a dependency

See original GitHub issue

My automated testing for the pyresample packages includes installing pyproj from pip (this is actually readthedocs doing the install, but still). When attempting to pip install pyproj I get:

Hm apparently it is already using pip 20+:

 Requirement already up-to-date: pip in /home/docs/checkouts/readthedocs.org/user_builds/pyresample/envs/310/lib/python3.7/site-packages (20.2.4)

This will be fun.

Edit: Got it. Old rtd config was using python setup.py install to install the package which uses the old egg/easy_install installation method
