Qt+OpenCV: Symbols not found for architecture x86_64

Question

I want to use the stereo-module of OpenCV, programming with Qt. When building my project, i get the following errors:

My setup:

• OpenCV 4.3.0 + contrib 4.3.0 compiled from source, used CMake GUI to make
• Qt Creator 4.11.0, Based on Qt 5.14.0 (Clang 10.0 (Apple), 64 bit)

My pro-file:

Who can help me?

According to the documentation for StereoSGBM it is part of the calib3d module, which is part of the contrib that you have mentioned already have.

I see you have linked against core, imgproc, imgcodecs and highgui but the calib3d is missing.
