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
