I can add the target that is looking for the source file, but that is 
about as much information as is available.  The problem is the final 
add_executable or add_library command just gets a list of sources as 
strings, and during the generate step the generator looks for the files. 
  All the handling of the source file names before they are passed to 
add_executable or add_library is just as strings, so there is no way to 
identify the first reference to a source file.
