Possiblity to pass custom argument to setup.py when installing a package

[mgreive]

It used to be possible to pass custom options with pip install that could be accesed in setup.py as described for example in this stackoverflow post. Since --install-options is now deprectated ( pypa/pip#11358) this is not possible anymore.

When trying to use --install-options pip suggests --config-settings settings as a workaround. Is it possible to access the value-key pair specified with --config-setting from within setup.py?

I posted a question regarding this on stackoverflow but I am starting to wonder if it is even possible to get the result I want with --config-settings. If this is not the case, does setuptools offer an alternative?
