What do you mean as "input", you mean a source file in
add_library or add_executable?

Don't know but I guess that now you can:

set_property(SOURCE blah.h PROPERTY GENERATED TRUE)
or
set_source_files_properties(blah.h PROPERTIES GENERATED TRUE)

I guess it should work even if blah.h is generated at CMake time.

Could you explain what do you mean by "blank file"?
