+# - Find SZIP library

+# Find the native SZIP includes and library
+# This module defines
+#  SZIP_INCLUDE_DIRS, where to find tiff.h, etc.
+#  SZIP_LIBRARIES, libraries to link against to use SZIP.
+#  SZIP_FOUND, If false, do not try to use SZIP.
+#    also defined, but not for general use are
+#  SZIP_LIBRARY, where to find the SZIP library.
+#  SZIP_LIBRARY_DEBUG - Debug version of tiff library
+#  SZIP_LIBRARY_RELEASE - Release Version of tiff library
