Opencv build issue with PyQt6

I’m trying to build OpenCV 4 with QT 6.8.1 and OpenVino.

First I built Qt 6.8.1 and OpenVino locally

> qmake --version
QMake version 3.1
Using Qt version 6.8.1 in /opt/qt/6.8.1/lib

> cat  /opt/intel/openvino_2024.6.0/runtime/version.txt
2024.6.0-17404-4c0f47d2335-releases/2024/6

Then I built OpenCV 4 with:

    export LDFLAGS="-L/opt/intel/openvino_2024.6.0/runtime/lib/arm64/Release -L/opt/onnx/onnxruntime/lib -L/opt/qt/6.8.1/lib"
    export CPPFLAGS="-I/opt/intel/openvino_2024.6.0/runtime/include -I/opt/onnx/onnxruntime/include -I/opt/qt/6.8.1/include"

… and …

    -D WITH_QT=ON -D WITH_OPENGL=ON \
    -D QT_MAKE_EXECUTABLE=/opt/qt/6.8.1/bin/qmake \

The cmake output shows

--   GUI:                           QT6
--     QT:                          YES (ver 6.8.1 )
--       QT OpenGL support:         YES (Qt6::OpenGL )
--     Cocoa:                       YES
--     OpenGL support:              YES (/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX15.2.sdk/System/Library/Frameworks/OpenGL.framework /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Deve

And it compiles but when I import cv2 in a python script I got errors like:

ImportError: dlopen(/Users/me/miniconda3/envs/opencv-venv/lib/python3.12/site-packages/cv2/python-3.12/cv2.cpython-312-darwin.so, 0x0002): Library not loaded: @rpath/QtGui.framework/Versions/A/QtGui
  Referenced from: <27DBDEE9-4DDD-3A97-8F56-BB1095E9F5C1> /opt/opencv/lib/libopencv_cvv.4.10.0.dylib

So then I created symlinks in my ${OPENCV-INSTALL-DIR}/lib/ dir
to all the “framework” dirs in ${QT-INSTALL-DIR}/lib/
and so far it seems to work.

cd /opt/opencv/lib
while read fw ; do ln -s /opt/qt/6.8.1/lib/$fw $fw ; done < <(ls -1 /opt/qt/6.8.1/lib/ |grep framework)

Is that the proper way to fix this or am I missing something in the build steps?
