+#   LIBAVIF_INCLUDE_DIRS - the directory containing the avif headers
+#   LIBAVIF_LIBRARIES - avif libraries to be linked
+#
+# The following cache variables may also be set::

+#   LIBAVIF_INCLUDE_DIR - the directory containing the avif headers
+#   LIBAVIF_LIBRARY - the avif library (if any)

+# Find include directory
