It uses SDL2, OpenAL, FFmpeg, zlib blast, and the EnTT, filesystem, and cxxopts submodules. git submodule update fetches those. Windows builds use vcpkg for sdl2, ffmpeg, and openal-soft, then cmake --build build. macOS runs apple/build.sh macos. The iOS path builds only the simulator. --path points at the game data, or the files go in a data directory with binks, fx, gfx, maps, and stronghold.mlb.",
