How do you use this script in combination with your setup_opencv_macos.sh?
I have probably the same issue as compiling openCV fails by using your setup_opencv_macos.sh.

This script effectively replaces that older shell script. What issues are you getting when you build OpenCV in your environment @jps05 ?
