I guess that you have libfluidsynth.so installed somewhere in /usr/lib/ and this one was compiled without alsa support. If this is the case, when starting ./fluidsynth_simple it doesnt find libfluidsynth.so in the current working directory and uses the one in /usr/lib/. Either remove that installation or set LD_LIBRARY_PATH like:
export LD_LIBRARY_PATH=/path/to/custom/libfluidsynth.so:$LD_LIBRARY_PATH Or build fluidsynth_simple with a statically linked libfluidsynth.a of which you know it was compiled with alsa support.
