If you're looking for guidance on how to build a cross-platform C++ game for both the web and desktop, this project is for you! It illustrates a modern (2025) CMake build script, and C++ bootstrapping using Emscripten. It includes SDL_image for loading textures, SDL_ttf for loading fonts, and SDL_mixer for loading and playing music and sound effects.
SDL version 2 was chosen because SDL_mixer did not yet have a version 3 release tag at the time this project was created. A separate project targeting SDL3 will be available once the full SDL stack has an official version 3 release!
