      # ships VS Enterprise which pre-sets a system-wide VCPKG_ROOT
      # pointing at its own (empty) vcpkg dir, and that pre-set value
      # wins over a job-level env in PowerShell expansions. We export
      # the right VCPKG_ROOT into $GITHUB_ENV inside the clone step
      # so every later step sees our copy.
      #
      # We rely on actions/cache for the installed Qt artifacts; the
      # vcpkg x-gha backend depends on the v1 GitHub Actions cache API
      # which has been deprecated, and a fresh runner image often does
      # not have ACTIONS_RESULTS_URL set for non-Node actions yet.
      # Setting "files" as the binary source means vcpkg will still
      # populate ${VCPKG_ROOT}/archives, which actions/cache then
      # snapshots along with installed/.
