how to pass setup.py arguments

[nekopsykose]

some projects have something like:

python3 setup.py build --system-lib-1

it's not clear how to pass the same kind of thing when just calling gpep517 build-wheel (setuptools backend). --config-json seems related, but it's not clear what corresponds to what exactly

I'm sorry, I've missed this bug report.

It's basically --config_json '{"--build-option": ["--foo1", "--foo2"]}'. That said, setuptools supports only passing global options and not specific arguments to commands, at least not without hacks.

pypa/setuptools#3896 is the upstream bug for documenting this.

(we usually ask upstreams to make configuration via envvars possible)
