Introduce
make_extension_module_extrawhich gets called during modulefile creation for every extension similar to
make_module_extra.This ensures it will also be called for parallel extension or --module-only builds.
Fixes #4647
I'm open for a better name but
make_module_extra_extensionsalready exists somake_module_extra_extensionmight be confusing.Currently the (now deprecated) feature is only used by the numpy easyblock to add the numpy includes to
$CPATH. So that easyblock needs to be updated. I'd argue that we shouldn't add the numpy includes as a regularpip install numpydoesn't do that either. So if a user updates the numpy in a virtualenv using our current approach might end up using headers from one numpy and libs/python files from another.However I'm not sure if (and why) other software we have already relies on that. One which did will be fixed by easybuilders/easybuild-easyconfigs#21467
