Proper dependencies handling, of course. Embedding external code is just plain 
bad practice.

Yes, a proper library only provides headers! If I need to recompile 
libgps_sock then I'm doing it wrong. Embedding is bad, really.

So by using libqgpsmm against Qt5 I get everything I need using just a 
precompiled distro package!
