Summary

Add a short note in the build instructions about using configure cache for faster local iteration.

Closes #1115

Changes

  • In getting-started/setup-building.rst, added guidance that ./configure -C (aka --config-cache) can speed up repeated configure runs by reusing probe results.

Why

A clean ./configure can be slow during edit-configure-build-test workflows; this note helps contributors discover an existing low-effort speedup.
