Review Comment:
   For pyprojects that have meson.build files which compile and install BOTH a 
shared library, and a python extension that links to the shared library, 
meson-python can internally package it in a wheel using the same tricks that 
auditwheel uses to bundle up completely third-party shared libraries.
   
   Namely, meson-python installs the shared library into a private directory in 
site-packages (.xxx.mesonpy.libs/) and uses patchelf to modify the extension 
module to search there for its shared library dependencies.
   
   You shouldn't need patchelf if that relocation isn't being done. Users of 
auditwheel are probably accustomed to installing patchelf anyway, though. :)
