Rouesvm/c---sdl-project ? reverse-engineered prompt

Build me a simple factory game in C++ using SDL3 and SDL_ttf.

I want a playable prototype where I can place basic machines on a map, connect them with lines or belts, and watch items move through the factory. It should have a clean game window, simple text UI, and use the assets folder for any images or fonts. Make it feel like an actual factory builder, even if the graphics are basic for now.

Please set it up so it can be built with CMake and runs as a normal desktop game. If you need current setup details for SDL3 or SDL_ttf, look up the latest docs online. Keep the code organized and make it easy to expand later with more machines, items, and UI panels.
