Test submodule in github action
@peterhashair Thanks for this. But looking at the output it seems the action is first running a checkout including the submodules and afterwards a switch to the commit the tests should run for. So far that's fine, but I guess you would also need to do a submodule update
afterwards, as otherwise the changes for the submodules won't be used. Or did I miss that?
@sgiehl add git submodule update --init --recursive
