Message at start: "Meld requires GtkSourceView 4.0 or higher"
when i start meld, the message pops up: "Meld requires GtkSourceView 4.0 or higher". I use ubuntu 22.10 and the actual meld main branch. Ubuntu has installed libgtksourceview-5-0 as default and i also installed libgtksourceview-5-dev, but this does not help.
