-def _get_shared_lib_path(*libnames: str) -> Optional[str]:
-    """
-    Return the full path to a shared library file installed in
-    ``$SAGE_LOCAL/lib`` or the directories associated with the
-    Python sysconfig.
-
-    This can also be passed more than one library name (e.g. for cases where
-    some library may have multiple names depending on the platform) in which
-    case the first one found is returned.
-
-    This supports most *NIX variants (in which ``lib<libname>.so`` is found
-    under ``$SAGE_LOCAL/lib``), macOS (same, but with the ``.dylib``
-    extension), and Cygwin (under ``$SAGE_LOCAL/bin/cyg<libname>.dll``,
-    or ``$SAGE_LOCAL/bin/cyg<libname>-*.dll`` for versioned DLLs).
-
-    For distributions like Debian that use a multiarch layout, we also try the
-    multiarch lib paths (i.e. ``/usr/lib/<arch>/``).
-
-    This returns ``None`` if no matching library file could be found.
