Build me a playable desktop version of the Royal Game of Ur in C++ for a school project. I want it to run in a simple window with a clean board, clickable pieces or easy controls, and the basic rules of the game so two people can take turns playing on the same computer.

Please make it feel polished enough to present in class, with a title screen or simple menu, clear turn indicators, move highlights, and a way to restart a match. Use raylib for the graphics, and keep it easy to build with CMake on Windows and Linux. If you need to check current raylib or CMake setup details online, go ahead.

I also want the code to be organized in a way that looks like an object oriented class project, not a single messy file. Include whatever assets or simple visuals are needed, but keep the game straightforward and focused on being fun, readable, and easy to run.
