The following is a table for project specific build flags using CMake:
| Flag | Description | Options | Default |
|------------------|-----------------------------------------------------------------|--------------------------------------------------------------------------------------|---------------------------------------------------------------------------------------------|
| `PLATFORM` | The platform to build for. | `SDL2`, `SOKOL` | `SDL2` |
| `RENDERER` | Graphics renderer. | `GL` for OpenGL 3, `GLES2` for OpenGL ES 2, `SOFTWARE` for a pure software renderer. | `GL` |
| `USE_GLVND` | Link against the OpenGL Vendor Neutral Dispatch libraries. | `ON`, `OFF` | `ON`, falling back to `OFF` if the libraries aren't found or an OpenGL renderer isn't used. |
| `MINIMAL_BUNDLE` | Do not include the music/intro video when building for the web. | `ON`, `OFF` | `OFF` |

| `DEV_BUILD` | Sets the assets/userdata path to the source directory. Useful when testing any changes. | `ON`, `OFF` | `OFF` |
