+# - Find libidn
+# Find the libidn library, and more particularly the stringprep header.
+#
+# This module defines the following variables:
+#   LIBIDN_FOUND  -  True if library and include directory are found
+# If set to TRUE, the following are also defined:
+#   LIBIDN_INCLUDE_DIRS  -  The directory where to find the header file
+#   LIBIDN_LIBRARIES  -  Where to find the library file
+#
+# For conveniance, these variables are also set. They have the same values
+# than the variables above.  The user can thus choose his/her prefered way
+# to write them.
+#   LIBIDN_INCLUDE_DIR
+#   LIBIDN_LIBRARY
