Build error when including MATLAB module #3886
Description
Warning: this may be duplicate with Issue #3781. However, since #3781 has not been addressed by anyone and little info was provided on that post, I repost the issue in hopes that it would be addressed.

Note, OpenCV and its contrib modules compile without errors when MATLAB module is disabled.
Conversely, I have tested with as much modules disabled to isolate the issue (shown below), but it also fails
#!/bin/bash

- What I have tried
toopencv_contrib/modules/matlab/CMakeLists.txt, addopencv_optflow
ocv_add_module(matlab BINDINGS
OPTIONAL opencv_core
opencv_imgproc opencv_ml
opencv_imgcodecs opencv_videoio opencv_highgui
opencv_objdetect opencv_flann opencv_features2d
opencv_photo opencv_video opencv_videostab
opencv_calib opencv_calib3d
opencv_stitching opencv_superres
opencv_xfeatures2d
opencv_xphoto
opencv_optflow
)
Then in bridge.hpp, fix
typedef cv::Ptr<DualTVL1OpticalFlow> Ptr_DualTVL1OpticalFlow; to
typedef cv::Ptr<cv::optflow::DualTVL1OpticalFlow> Ptr_DualTVL1OpticalFlow;
This did not resolve the issue. There are multiple other errors regarding operator =, and some seem to originate from cpp files generated during build by modules/matlab/generator/gen_matlab.py
I have failed to fix the errors that were generated one after another when trying to mod the matlab module code and its generator scripts myself.
Is the matlab module of opencv_contrib deprecated or currently unsupported?
