Integrating YOLO into C++

I am trying to integrate YOLO into my C++ code with opencv. I have done extensive research including going through this code https://www.learnopencv.com/deep-learning-based-object-detection-using-yolov3-with-opencv-python-c/. The code on the website works fine but does not invoke GPU making it pretty slow. Using the code on the official site works perfect with up to 30 fps on my GPU but is a problem integrating in my C++ code. The wrappers are not working for me and throwing an error whenever I call any darknet defined attribute. Anyone with experience or knowledge on how to handle this, your contribution will be immensely appreciated.
