As you have observed, this fails because Setuptools does not correctly
handle the ‘setup_requires’ option
<URL:https://github.com/pypa/setuptools/issues/457>.

All of the build dependencies, *including* the ones specified in
‘setup_requires’?

To avoid the Setuptools bug, the PyPA recommends dropping the
‘setup_requires’ option and instead specifying build dependencies in a
PEP 518 formatted metadata file
<URL:https://github.com/pypa/setuptools/issues/293>.
You could create such a specification (by adding a metadata file),
ensure those dependencies are also present locally, and meanwhile
present the maintainers of this project with your merge request to add
that metadata file.
