[jira] [Created] (ARROW-18341) [Doc][Python] Update note about bundling Arrow C++ on Windows

Alenka Frim created ARROW-18341:
-----------------------------------

             Summary: [Doc][Python] Update note about bundling Arrow C++ on Windows
                 Key: ARROW-18341
                 URL: https://issues.apache.org/jira/browse/ARROW-18341
             Project: Apache Arrow
          Issue Type: Improvement
          Components: Documentation, Python
            Reporter: Alenka Frim
            Assignee: Alenka Frim
             Fix For: 11.0.0


There is a note on the python development page under Widnows section about bundling the Arrow C++ libraries with Python extensions:

[https://arrow.apache.org/docs/dev/developers/python.html#building-on-windows]

This note can be revised:
 * if you are using conda, the fact that Arrow C++ libs are not bundled is fine since conda will ensure those libs are found.
 * If you are not using conda, you have to ensure those libs can be found: either by updating {{PATH}} (every time before importing pyarrow), or either by bundling them (... using the {{PYARROW_BUNDLE_ARROW_CPP}} env variable instead of {{{}--bundle-arrow-cpp{}}}). With the caveat those won't be automatically updated when rebuilding the arrow-cpp libs then.
