Besides the argument of tracking changes, portability comes in mind as well.
Does XCode, Visual Studio, Eclipse (with managed Makefile)
etc... do handle globbing as well ?

CMake should be able to generate project files for all these build
system so that relying on the fact that Make may handle globbing is not enough
for making it work for CMake.

Does your VCS (git, cvs, svn,...) do globbing for adding/removing files ?
Probably not and for good reasons, the same rule apply for CMake.

What you 'could do' is to craft some scripts (CMake or else) that
may automagically update the extensive list of sources in your CMakeLists.txt.
This script may be launched by a CMake custom target of yours, e.g.
then you'll be able to do

make up_src_list

instead of editing the CMakeLists.txt manually,
that said I doubt it would be  worth the effort.

My point of view is that globbing for source is seldom useful unless
the sources files are generated.

My opinion though.
