Note: I was talking about the generated source files, not the file
you're reading in again. This ought to work and actually works just fine
for kdevelop where we use a parser-generator to generate some sources
(using custom_command and OUTPUT). And it works with the source-file
property for the java plugin which uses flex to generate a lexer source
file. 

And it works fine with a small test too:
,----
| set_source_files_property( foo.cpp PROPERTIES GENERATED TRUE )
| 
| add_executable( bar foo.cpp )
`----
