dev: Fix wheel building during installation from PyPI #61
Description
There is a difference in the behavior of pip install based on the package specification. When installing form Git, it installs the dependencies before building the wheel. When installing from PyPI, it first tries to build the wheel, and only then it installs the dependencies. Here are relevant excerpts:
