I tried to start from this sample project.

pip install . works fine,

However, pip install -e . failed.

ModuleNotFoundError: No module named 'hello._hello'

Here's the info about my system and evironment.

By the way, python setup.py develop works also fine, seems that pip install -e . does not trigger the compilation of C++ sources. So this seems not to be a problem with scikit-build. Does anybody know a workaround to make pip install -e . work?
