make-prerequisites-changed

A GitHub Action that checks whether any prerequisite of a Makefile target changed since a given base commit. Combines colluca/list-make-prerequisites with tj-actions/changed-files to gate a job on whether its actual Make dependencies changed, instead of a hand-maintained list of glob patterns.

Usage

  id: changed
  with:
    target: my-target
    flags: --recursive

  run: make my-target
