4. Copy the resulting ioquake3.app in /build/release-darwin-universal2
to your /Applications/ioquake3 folder.
For Web, building with Emscripten
1. Follow the installation instructions for the Emscripten SDK including
setting up the environment with emsdk_env.
2. Run `emmake make debug` (or release).
3. Copy or symlink your baseq3 pk3 files into the `build/debug-emscripten-wasm32/baseq3`
directory so they can be loaded at run-time. Only game files listed in
`client-config.json` will be loaded.
4. Start a web server serving this directory. `python3 -m http.server`
is an easy default that you may already have installed.
5. Open `http://localhost:8000/build/debug-emscripten-wasm32/ioquake3.html`
in a web browser. Open the developer console to see errors and warnings.
6. Debugging the C code is possible using a Chrome extension. For details
see https://developer.chrome.com/blog/wasm-debugging-2020

# OpenGL ES support
The opengl2 renderer (the default) supports OpenGL ES 2+. Though there
are many missing features and the performance may not be sufficient for
embedded System-on-a-Chip and mobile platforms.
The opengl1 renderer does not have OpenGL ES support.
The opengl2 renderer will try both OpenGL and OpenGL ES APIs to find one that
works. The `r_preferOpenGLES` cvar controls which API to try first.
Set it to -1 for auto (default), 0 for OpenGL, and 1 for OpenGL ES. It should be
set using command line arguments:
