Since uvicorn has a proper pyproject.toml, you will want to use the new
"PEP-517" classes available since 'kirkstone' Yocto Project release.
You want to look at the pyproject.toml "build-backend" line:
https://github.com/encode/uvicorn/blob/master/pyproject.toml#L3
build-backend = "hatchling.build"

This tells you which of the "PEP-517" classes to use.

This class was introduced in the 'langdale' Yocto Project release.
