> mailing list discussion.
> Certain sections of setup.py assume a specific location of the C++ libraries.
> Removing this hard assumption will simplify PyArrow builds significantly. As
> far as I could tell these assumptions are made in the
> {{build_ext._run_cmake()}} method (wherever bundling of C++ libraries are
> handled).
> # The first occurrence is before invoking cmake (see line 237).
> # The second occurrence is when the C++ libraries are moved from their build
> directory to the Python tree (see line 347). The actual implementation is in
> the function {{_move_shared_libs_unix(..)}} (see line 468).
> Hope this helps.
