commit 8b6adbffead83c9d77c493174d0f5b6a97f2a9e9
Author: Thomas Moschny <thomas.moschny@gmx.de>

    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.
