# SDL is weird in that instead of just dynamically linking with
# libraries when you `--enable-*` (or when `configure` finds) them
# it `dlopen`s them at runtime. In principle, this means it can
# ignore any missing optional dependencies like alsa, pulseaudio,
# some x11 libs, wayland, etc if they are missing on the system
# and/or work with wide array of versions of said libraries. In
# nixpkgs, however, we don't need any of that. Moreover, since we
# don't have a global ld-cache we have to stuff all the propagated
# libraries into rpath by hand or else some applications that use
# SDL API that requires said libraries will fail to start.
#
# You can grep SDL sources with `grep -rE 'SDL_(NAME|.*_SYM)'` to
# list the symbols used in this way.
