Contributor guide
Research direction
Start by reproducing configuration with ARROW_PYTHON=ON in an environment where NumPy is missing. Inspect the configuration path for the Python extension support libraries and identify why NumPy is required. Done means the C++ project configures successfully without NumPy when only those support libraries are being built.
