The problem is tkfontawesome doesn't have a pyproject.toml. Pip now builds in isolated mode by default, which means that it's incorrectly setting up the environment. (In Python 3.12, both distutils and setuptools won't be in default environments either, by the way!) Either a pyproject.toml should be added with the following content:

[build-system]
requires = ["setuptools", "scikit-build"]
build-backend = "setuptools.build_meta"

or you can pass --no-build-isolation (if using pip) / --no-isolation (if using build).

Thanks @henryiii.
