Where I can find meld.ui.gladesupport
In the ui files in meld repository there's this requirement:
<!-- interface-requires meld.ui.gladesupport 0.0 -->
And glade cannot manage meld ui templates
Failed to load /home/roberto/prj/meld-master/meld/resources/ui/appwindow.ui.
The following required catalogs are unavailable: meld.ui.gladesupport
Where I can find these data or how can I install ?
