Hi Marcel
Yes, I appreciate very much your answer. You've solved the whole of my 
actual doubts. You said you didn't understand why I don't just use 
--enable-test from the bluez-utils configure script. Well that's easy: 
because I didn't know about the possibility. Anyway, it's helpful for me 
  in order to learn.
Thanks Marcel
