You could give your files a file ending like 'output.c' instead of  
just 'output'. Or, if that is the normal file naming, set the LANGUAGE  
file property and the LINKER_LANGUAGE target property.

You have an additional problem: you use target 'io' before it is  
defined. If the io library is not installed, yet, this will fail.
