> I found that I had to add {{-Wdocumentation}} to {{ARROW_CXXFLAGS}} to replicate docstring-related failures in CI. I'm not sure why this is being set in Travis CI but not locally (with BUILD_WARNING_LEVEL=CHECKIN), but we should make it consistent and also document that it is a requirement in the C++ development Sphinx documentation
