Description: use the system-wide minizip instead of the embeeded one if found.
Forwarded-Upstream: It was provided by upstream: http://bazaar.launchpad.net/~widelands-dev/widelands/b19-debian/revision/8147
.
Thanks to Fòram na Gàidhlig for the patch.
I just added this line to make its use easier:
set(CMAKE_MODULE_PATH ${CMAKE_MODULE_PATH} ${CMAKE_HOME_DIRECTORY}/Modules)
