Doesn't that generally end up using setup.py as well?
From my understanding, build ends up calling the build-backend, which defaults to setuptools.build_meta:__legacy__, which is setup.py.
I know there are other backends, but they seem very specialized to a certain project's needs.
I think there's a cmake backend too, but I don't like requiring my customers to install cmake first, and that dependency can't be expressed in pyproject.toml.
I had hoped that redo (https://redo.readthedocs.io/en/latest/) would become popular, as a small, simple, pure-Python Makefile replacement, and that there would be a back-end using it, but neither happened.
My specific needs for a backend is to support and configure a code-generation step when building my C extension. The full code generation is >10MB, which handles all 3x24 or so different specialized implementations of the core algorithm. This takes a while to compile, so during development I use a slower, general-purpose implementation.
