Building package with non conda-forge packages

[giannischatzo]

I am in the situation where a package I want to build has three different kind of dependencies:

1. PyPI dependencies that map to conda-forge packages
2. private python packages hosted in Cloudsmith (they're built using uv and I am using index-url for installation)
3. conda only packages

Is pixi build currently supporting these kind of dependencies? Is there any documentation describing how such package can be built?
