CMake uses a simple conversion from glob to regex, the code for that can 
be found here:

http://public.kitware.com/cgi-bin/viewcvs.cgi/Source/kwsys/Glob.cxx?revision=1.16&root=CMake&view=markup

It does a simple glob with *,?, and [], and that is about it.

The best thing to do would be to try using a glob expression from a bash 
shell and ls.  For example, the first one you gave does not work 
.[hi]pp.  It was added to cmake to give simple globs like *.c *.cxx *.h, 
etc.
