A somewhat comprehensive guide on how to build the game from source.
This might contain modifications to the source code that make it not interoperable with the base game.

Install Visual Studio 2023
Install CMake
Optionally, Install QT 5.6.0
Optionally, Install Ninja if using Visual Studio Code (pip can be used to install it as well)

Run scripts\windows\setup64.bat
A solution should be generated in the build folder
Open it and click Build (shortcut: CTRL+B)

Open a vcvars64 window (x64 Native Tools Command Prompt for VS 2022)
Run scripts\windows\setup64-ninja.bat

A ninja project should be generated in the build folder
Simply run cmake --build .
