      # app/src/CMakeLists.txt), so no cv::cuda / CUDASIFT path can actually
      # execute there -- everything falls back to CPU and the run just repeats
      # the coverage the non-CUDA job already gives, on the same sources. It
      # used to cost more than it returned: the two cv::cuda-touching tests
      # (test_util3d_features, test_localgrid) had to be excluded because lazy
      # CUDA-init stalled them past the 300 s timeout, and once WITH_ZED=ON was
      # added to this job every remaining corelib test died in the loader with
      # 0xc0000135 (STATUS_DLL_NOT_FOUND) before reaching main(): rtabmap_core
      # links sl_zed64.dll, which imports the driver-only nvcuvid.dll /
      # nvEncodeAPI64.dll that a driver-less runner does not have.
      #
      # So this job compiles, links and packages the CUDA artifact; the
      # non-CUDA job is what verifies behaviour. Same reason the Info step
      # below is skipped here.
