cmake generates circular dependencies

[GoogleCodeExporter]

Not sure if it's a bug in my cmake (Ubuntu 2.8.7 and 2.8.9), but it ends up 
generating makefiles where message.pb.c depends on message.pb.c

Changing the custom command depends to use the full path of message.pb files 
fixes it.

Thanks, I merged the patch. I don't use cmake myself, but the change seems 
sensible and if it works for you, it'll probably help someone else also :)
