Install YOLO with OpenCV (2019)

1. get cmake
2. get opencv and opencv-contrib
3. read how to configure opencv with cmake and here at pyimagesearch
4. remember to configure cmake with extra options:

• Add OPENCV_ENABLE_NONFREE=ON
• Add OPENCV_EXTRA_MODULES_PATH=<your contrib/modules folder>
• (if you run into problems: delete cache, regenerate, reconfigure)

5. follow instructions to build yolo with opencv support https://www.learnopencv.com/deep-learning-based-object-detection-using-yolov3-with-opencv-python-c/ https://www.pyimagesearch.com/2018/11/12/yolo-object-detection-with-opencv/
