Building Can't find OpenCV-CUDA library

I am building your code and get errors in linking:


[build] /usr/bin/ld: CMakeFiles/run_inference_benchmark.dir/src/main.cpp.o: in function `main':
[build] /mnt/DATA/MP/Software/Inference/cyrus-tensorrt-cpp-api/src/main.cpp:82: undefined reference to `cv::cuda::cvtColor(cv::_InputArray const&, cv::_OutputArray const&, int, int, cv::cuda::Stream&)'

I made changes to your CMakeLists.txt to adapt to my installation. Attached here
