  # Note on CMAKE_ARGS:
  #   CMake args are adopted from OpenCV.js (https://github.com/opencv/opencv/blob/4.x/platforms/js/build_js.py)
  #   But we support more modules than OpenCV.js.
  #
  # List of OpenCV modules can be found at: https://docs.opencv.org/4.x/
  # Build configs can be found at: https://docs.opencv.org/4.x/db/d05/tutorial_config_reference.html
