[jackhill/guix/guix.git] / gnu / packages / patches / widelands-system-wide_minizip.patch

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)
