Pip not able to install climetlab (v0.11.31) in windows with Python 3.7 : HDF5 headers not found

The title is quite explicit :p . I get this error in the tests for the release of a new version of the EUMETNET benchmark climetlab plugin. Is climetlab still supported in Python 3.7?

See the error log here:

Yes, droping support for Windows python 3.7 would make sense IMO, depending on your users of course.

You can achieve this in the .github/workflow yaml file using exclude as in:

    strategy:
      fail-fast: true
      matrix:
        platform: ["ubuntu-latest", "macos-latest", "windows-latest"]
        python-version: ["3.7", "3.8", "3.9", "3.10"]
        exclude:
          - platform: "windows-latest"
            python-version: "3.7"

Indeed, apparently, the issue comes from the netcdf4 package, there is not much that we can do from climetlab.
