## Compile from source
- Clone the Git repo. Do NOT download it as ZIP, that won't work.
- Update the submodules and run `premake5 vs2019` or simply use the delivered `generate.bat`.
- Visual Studio Properties -> Linker -> Input -> Module Definition File -> add module.def located in src folder
- Update the submodules and run `premake5 vs2022` or simply use the delivered `generate.bat`.
- Build via solution file in `build\mw3-server-freezer.sln`.
