Suvayu Ali created ARROW-4930:
---------------------------------

             Summary: Remove LIBDIR assumptions in Python build
                 Key: ARROW-4930
                 URL: https://issues.apache.org/jira/browse/ARROW-4930
             Project: Apache Arrow
          Issue Type: Improvement
          Components: Python
    Affects Versions: 0.12.1
            Reporter: Suvayu Ali


This is in reference to (4) in [this|http://mail-archives.apache.org/mod_mbox/arrow-dev/201903.mbox/%3C0AF328A1-ED2A-457F-B72D-3B49C8614850%40xhochy.com%3E]
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.
