+# This module finds if IMLIB2 is available and determines where the
+# include files and libraries are.
+# On Unix/Linux it relies on the output of imlib2-config.
+# This code sets the following variables:
+#
+#
+#
+# IMLIB2_FOUND              = system has IMLIB2 lib
+#
+# IMLIB2_LIBRARIES          = full path to the libraries
+#    on Unix/Linux with additional linker flags from "imlib2-config --libs"
+#
+# CMAKE_IMLIB2_CXX_FLAGS    = Unix compiler flags for IMLIB2, essentially "`imlib2-config --cxxflags`"
+#
+# IMLIB2_INCLUDE_DIR        = where to find headers
+#
+# IMLIB2_LINK_DIRECTORIES   = link directories, useful for rpath on Unix
+#
