I didn't claim you should have CMake do any such thing automatically, did I say anything to suggest otherwise?
The workflow I intend to use is: 1. I create src/foo.cc 2. I type a command (which will delete the build directory, recreate it and rerun cmake, which will bring everything up to date) I put it to you that this is strictly better (both easier and less error-prone) than the workflow other people here are suggesting, which is: 1. You create src/foo.cc 2. You edit the list of files by hand 3.
