libmusicbrainz in kdemultimedia

[Anne-Marie Mahfouf]

Hi people,

Currently the cmake check in kdemultimedia requires libmusicbrainz version 
2.1.5

Are libmusicbrainz versions > 3 supported (is the check badly done?)
or is it only version 2.1.5 which is required? In that case, please add an 
output telling the user that. Many users have versions >3 and do not 
understand why kdemultimedia is not detecting it.

Thanks, best regards,

Anne-Marie
