+.. code-block:: cmake
+ find_package_message(<name> "message for user" "find result details")
+This function is intended to be used in FindXXX.cmake modules files.
+It will print a message once for each unique find result. This is
+useful for telling the user where a package was found. The first
+argument specifies the name (XXX) of the package. The second argument
+specifies the message to display. The third argument lists details
+about the find result so that if they change the message will be
+displayed again. The macro also obeys the QUIET argument to the
+find_package command.
