On top of this great anwser. One more thing to notice is that --install-options doesn't work with wheel

Since version 7.0 pip supports controlling the command line options given to setup.py via requirements files. This disables the use of wheels (cached or otherwise) for that package, as setup.py does not exist for wheels.

python setup.py bdist_wheel install -your-options

To customize the install phase and this will affect the .dist-info of the wheel package.
