Nowadays, pyproject.toml becomes the standard configuration file for packaging. Compare with the old setup.py, it adds two feature pep517 and pep518.

pep517 defines two hooks: build_wheel and build_sdist, which is required to build the package from source. Each build backend must implement these two hooks. It makes it possible to create other build backend such as flit or poetry.

[build-system]
# Defined by PEP 518:
requires = ["flit"]
# Defined by this PEP:
build-backend = "local_backend"
backend-path = ["backend"]

Besides setuptools, there are some other build back-end such as hatchling and flit. You can find the example here: Python Packaging Uer Guide - Choosing a build backend
