+Subject: [PATCH] Normalize icon path names (fixes #869).
+
+The elements in ${icon_sources}, as returned by file(GLOB ...) contain
+double slashes, could be a bug in cmake. This causes building with
+cmake 2.8.4 to fail, due to dependency problems lateron.
+
+This patch works around the issue by normalizing all path names in
+${icon_sources} while appending them to ${ALL_ICONS}, thereby removing
+the double slashes.
