From d250b714f8eb5a60bb048830e723ac76f06215b7 Mon Sep 17 00:00:00 2001 From: Jorgen Lind Date: Thu, 14 Nov 2013 13:22:13 +0100 Subject: Move wayland into a client directory not under the plugins src folder And make wayland common files into a library, exporting all classes. Now there is no need to do bulild hacks to make your own version of the wayland plugin.
