   Thanks for tracking this down.  Yes, the LV2 stuff can use gtk2, but 
it doesn't need it.  You should be able to install lilv-devel without 
gtk2-devel and that might work.  Let me know how it goes if you try it.

   Note: A fresh clone shouldn't be necessary.  Just delete your build 
directory, create a new one, switch into it and run cmake again.

Ted.
