The process is based on this tutorial by Anindya for the step-by-step process with CMake GUI and this tutorial by James Bowley for the process with command line CMake and some troubleshooting. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. To create a new C++ project in Eclipse you need to install CDT plugin first (or use the Eclipse IDE for C/C++ Developers). OpenCV is a very extensive and incredibly powerful library for (real-time) computer vision, including object detection, motion tracking, and camera calibration.
