 - I get some warnings because of useless dependency, so I thought it would
   be a good idea to notify you guys

     dpkg-shlibdeps: warning:
     debian/drumgizmo/usr/lib/x86_64-linux-gnu/drumgizmo/input/jackmidi.so
     contains an unresolvable reference to symbol XML_SetUserData: it's
probably a plugin

     dpkg-shlibdeps: warning: 14 other similar warnings have been
skipped (use -v to see them all)

     dpkg-shlibdeps: warning: package could avoid a useless dependency if
    
debian/drumgizmo/usr/lib/x86_64-linux-gnu/lv2/drumgizmo.lv2/drumgizmo.so
was
     not linked against libz.so.1 (it uses none of the library's symbols)

     dpkg-shlibdeps: warning: package could avoid a useless dependency if
    
debian/drumgizmo/usr/lib/x86_64-linux-gnu/drumgizmo/input/midifile.so
was not
     linked against libglib-2.0.so.0 (it uses none of the library's symbols)

Note by deva: libglib is a requirement in the libsmf.pc file. The rest have been added/removed accordingly.
