PongooDev/OGS-12.41 — reverse-engineered prompt

I want you to take this old C++ project and get it into a state where I can open it, build it, and run it without guessing what to do. It looks like a Visual Studio solution, but the README is basically empty, so please inspect the code and figure out what this app is supposed to be, what parts are missing, and what needs to be fixed to make it work on a normal Windows dev setup.

If there are outdated project settings, broken includes, missing libraries, or compile errors, please clean that up in the repo instead of just describing the problems. If something can’t be fully finished because files are missing, stub or document it clearly so the project still builds as far as possible.

Also add a simple README that explains what the program is, how to build it, how to launch it, and any setup steps in plain English. If you need to, look up current docs online, but keep the result practical and easy for a non expert to use.
