-# This module defines
-#  ZLIB_INCLUDE_DIRS, where to find zlib.h, etc.
-#  ZLIB_LIBRARIES, the libraries needed to use zlib.
-#  ZLIB_FOUND, If false, do not try to use zlib.
-#
-# This FindZLIB is about 43 times as fast the one provided with cmake (2.8.x),
-# because it doesn't look up the version of zlib, resulting in a dramatic
-# speed up for configure (from 4 minutes 22 seconds to 6 seconds).
-#
-# Note: Since this file is only used for standalone, the windows
-# specific parts were left out.
