After installing openssl/zlib, run 'pip install ssh2-python'
The stack trace from pip looks like this:

ERROR: Failed building wheel for ssh2-python
I'm also not able to build using the system libssh2 (it doesn't prompt for a path, but I installed in /usr/local to make it happy). That fails linking saying it can't find libcryptoAD64.lib, which I find no reference to anywhere. I tried building from the source as well, editing setup.py to set runtime_library_dirs = [] and that fails for some other reason.
From source builds on Windows are a PITA - good luck. Best to use the pre-made wheels up to python 3.8. 3.9 is still not officially released.
Can try to follow from source instructions here after installing libssh2 - see windows CI configuration
General Windows question, not an issue with library - out of scope for issue tracker.
I was thinking 3.9 should have worked. I dropped back to 3.8 and everything went perfectly. Thanks!
