How to add OpenCV functions in CarlaUE4?

[yonglei123]

I added the OpenCV library functions in the CMakeLists.txt in LibCarla, and modified CarlaCameraPublisher.cpp and CarlaCameraPublisher.h. The libcarla_fastdds.a compiled successfully.
In Carla.Build.cs, I added:

PublicAdditionalLibraries.Add("/usr/lib/x86_64-linux-gnu/libopencv_core.so");
PublicAdditionalLibraries.Add("/usr/lib/x86_64-linux-gnu/libopencv_imgproc.so");
PublicAdditionalLibraries.Add("/usr/lib/x86_64-linux-gnu/libopencv_imgcodecs.so");
PublicAdditionalLibraries.Add("/usr/lib/x86_64-linux-gnu/libopencv_highgui.so");

But when compiling with make launch ARGS="--ros2 --editor-flags='--ros2'", I get the following error:

[68/77] Link (lld) libUE4Editor-HoudiniEngineEditor.so
20 warnings generated.
[69/77] Link (lld) libUE4Editor-Carla.so
ld.lld: error: undefined symbol: cv::imshow(std::__1::basic_string<char, std::__1::char_traits, std::__1::allocator > const&, cv::_InputArray const&)

Can anyone help me see what the problem is?
