I've been experimenting with the new macros for Python packages, and
ran into some issues building Sphinx docs for compiled extensions.
When building docs, one usually has to be able to import the project.
When the project uses compiled extensions, it is not sufficient to
point to the original unpacked sources, but instead must point to the
built ones. However, since the new %pyprojec_wheel creates a wheel, I
don't know how to do this properly.
Setting e.g., PYTHONPATH=/path/to/*.whl doesn't seem to work (it seems
to load everything else but the shared library):
+ pushd docs
~/build/BUILD/pikepdf-2.16.1/docs ~/build/BUILD/pikepdf-2.16.1
++ ls
/builddir/build/BUILD/pikepdf-2.16.1/docs/../pyproject-wheeldir/pikepdf-2.16.1-cp310-cp310-linux_x86_64.whl
+
PYTHONPATH=/builddir/build/BUILD/pikepdf-2.16.1/docs/../pyproject-wheeldir/pikepdf-2.16.1-cp310-cp310-linux_x86_64.whl
+ sphinx-build-3 . ../html
