### Rationale for this change Currently, when building pyarrow from source, one needs to manually enable the optional components through setting `PYARROW_WITH_...` environment variables. However, we could also make a default choice of components based on which ones where enabled in the Arrow C++ build. ### What changes are included in this PR? Set defaults for the various `PYARROW_BUILD_<component>` based on the `ARROW_<component>` setting. Keep the current `PYARROW_WITH_<component>` environment variables working to allow to override this default. One minor unfortunate consequence is that if you change your Arrow C++ build (eg enable a new component), you need to do a clean python build, otherwise CMake is still getting the old options (those option defaults are cached? Not sure if there is a way to solve this) ### Are these changes tested? <!-- We typically require tests for all PRs in order to: 1. Prevent the code from being accidentally broken by subsequent changes 2. Serve as another way to document the expected behavior of the code If tests are not included in your PR, please explain why (for example, are they covered by existing tests)? --> ### Are there any user-facing changes?
