+#
+# This function is similar in nature to configure file, except that it takes

+#
+# The CMake cache of the image will only be re-written in case there are
+# variables which has been updated as part of the call.
+#
+# Only variable of the form `@VAR_NAME@` will be updated.
+#
+# IMAGE: image name identifying the cache to update.
