Subject: [PATCH] cmake: link against the exported SDL3 and SDL3_mixer targets
The link line referenced ${SDL3_LIBRARIES} and ${SDL3_mixer_LIBRARIES},
variables that the SDL3 / SDL3_mixer 3.2 CMake config packages do not
define. As a result the executable failed to link with a long list of
undefined references to the SDL and MIX_* symbols.
The config packages instead export the imported targets SDL3::SDL3 and
SDL3_mixer::SDL3_mixer (which also carry the correct include directories
and transitive dependencies). Link against those.
