Issue
Is there a way to use a library that I built from source in virtualenv? All user documentation is about pip install normally. One option is to use --system-site-packages since library is built from source globally. But I don't want that.
Solution
I solved the problem by
pip install -e /path/to/package --no-binary :all:
