opencv_catkin make error SURF_CUDA
Hello, there. This the first time I ask for help on ANSWER ROS. THANK YOU. I have some problems with an open source github project. The address of the project is link text I encountered some errors when I implemented the command "catkin build depth_segmentation". It returns the feedbacks like this:
