The benefit is that CMake re-runs when new files are added because you 
have to edit the cmake file.  There is no way right now to have CMake 
auto re-run when a file is added to a directory.  That is why the docs 
recommend not using glob.

To implement this you would have to figure out a very efficient way to 
check for new files in a directory every time the build is done.  In 
your case you would have to figure out how to integrate that into visual 
studio.  VS has no way to "watch" a directory so you would have to run 
cmake --check-dirs every time a build is run from VS.
