[jira] [Created] (ARROW-8068) [Python] Externalize option whether to bundle zlib DLL in Python packages

Wes McKinney created ARROW-8068:
-----------------------------------

             Summary: [Python] Externalize option whether to bundle zlib DLL in Python packages
                 Key: ARROW-8068
                 URL: https://issues.apache.org/jira/browse/ARROW-8068
             Project: Apache Arrow
          Issue Type: Improvement
          Components: Python
            Reporter: Wes McKinney


I ran into an esoteric situation in ARROW-8015 where I built the C++ library with all bundled dependencies including zlib. I then build a Python wheel, but the Python build failed when using {{PYARROW_BUNDLE_ARROW_CPP=1}} because it could not find {{zlib.dll}}. The failure points were both in CMakeLists.txt and in setup.py.

Perhaps this situation will only arise esoterically, but we may want to add a flag to toggle off the zlib bundling behavior
