# SDL 3.4.18: the library the sdl3 port (src/hosted/sdl3) opens its window,
# reads input and plays audio through. Distributions package SDL3 too late
# or not at all (Linux Mint 22.3 has only SDL2), so it is built from the
# release source as a static library into toolchains/opt/sdl3; the programs
# link it in and run without an SDL3 on the machine. SDL loads the X11,
# Wayland, PulseAudio, PipeWire and ALSA client libraries at run time, so
# their headers must be present when it is built or those backends are left
# out (the dummy video and audio drivers the gates use are always there).
