Yes, that is the only way to make it work right now.  It would be nice 
to be able to add an arbitrary file that cmake would re-run when it 
changes.  Please create a feature request for this.  However, for now 
configure_file input is the only way to get your files in the list of 
files that are checked with each make run.

Problem is CMake is not running at build time.  It creates makefiles and 
it is done.   Even if you could run the glob, that would not solve your 
problem.  The exception to this rule is that cmake is re-run if any of 
its input files (configure_file, include, CMakeLists.txt, etc) are 
changed.
