%pyproject_buildrequires -r doesn't work. It says:

 ValueError: build backend cannot provide build metadata
 (incl. runtime requirements) before buld

Except for the typo [3], this is the expected behavior for a build backend 
that does not support the prepare_metadata_for_build_wheel hook. Bummer, but 
fair.


We can RFE PyQt-builder to add that hook.


As a start to tackling these problems, I sent this RFE upstream.  It looks 
like it should be relatively easy to implement, as far as I can see.


Miro, do you know any examples of Fedora packages that are using PEP-517 
build systems that build extension modules (successfully)?
