      # Naming convention: {platform}-{additional description}-{build type}
      #   - {platform} is the client platform/framework, which may differ from 
      #     the build platform. Specify both if applicable, e.g., "qt5-macos".
      #   - {additional description} optionally describes the compiler or other
      #     unique aspect of the build environment.
      #   - {build type} is typically "debug" or "release".

  # Add this step to all regular jobs to enable skipping of certain non-code-related changes.
  #
  # Do not include this step in nightly or release deployment jobs.
  #
  # To make a job potentially skippable on changes unrelated to its platform, it must:
  #   - Target one of the skippable platforms: Android, iOS, or macOS.
  #   - Have a job name that begins with a supported platform name.
  #   - Not be related to core functionality or rendering tests. Job names that
  #     contain "render-tests" cannot be skipped by platform changes.
  #
  # See the script in the following step for how to implement support for other platforms.
