PDM alternative to pip's --config-settings option

[amolenaar]

Hi,

I'm working on a meson-python based project: PyGObject. PDM seems like a good tool to manage venvs and the installation process.

For Meson-python to work well, I enabled the --no-isolation option in pyproject.toml.
I want to make debug builds when building with PDM. When installing with pip, I use pip install --no-build-isolation --config-settings=setup-args="-Dbuildtype=debug" -e '.[dev]'. This allows me to create debug builds when developing PyGObject, while normal release builds are made when PyGObject is installed as a dependency.

Is there an alternative to pip's --config-settings option in PDM?

(It may be more appropriate to support this from meson-python, but i have to start somewhere 😉 )
