install-from-source.yml

# Install esmvalcore from source on different OS's
# and different Python version; test locally with
# act: https://github.com/nektos/act
# Example how to setup conda workflows:
# https://github.com/marketplace/actions/setup-miniconda
# Notes:
#  - you can group commands with | delimiter (or &&) but those will be run
#    in one single call; declaring the shell variable makes the action run each
#    command separately (better for debugging);
#  - can try multiple shells eg pwsh or cmd /C CALL {0} (but overkill for now!);
