cftime does not compile from wheel on Windows Server 2019

[cphyc]

cftime is an upstream dependency of the yt project (http://yt-project.org). Since the release of cftime 1.3.1, our testing infrastructure is however unable to build cftime (from pip). Here is the backlog:

  ----------------------------------------
  ERROR: Failed building wheel for cftime
ERROR: Could not build wheels for cftime which use PEP 517 and cannot be installed directly

Here is the detail of our environment:

• cftime 1.3.1
• OS: Windows (Microsoft Windows Server 2019)
• Python 3.8 and 3.9 (haven't tested other versions).
• Using conda version : 4.9.2 (used to setup the env. not, to install cftime).

Note that cftime 1.3.0 works great.

Extra notes

Here is a link to a failing build https://github.com/yt-project/yt/pull/2978/checks?check_run_id=1720969048.

That's because there were no windows wheels uploaded to pypi yet for 1.3.1, so pip tried to build from source. The windows wheels are up now, so please try again.

I can confirm the issue is now fixed, closing this issue. Thanks!
