FILE does recalculate the GLOB every time CMake is run, but CMake is not invoked 
every time you type make.  CMake is ran once to setup the build directory, but 
after that when you run make it will call cmake only if a CMakeLists.txt is 
modified.

So the only way to run the FILE command at each build would be to run cmake at 
every build.  This can be done, but it would be a waste time.
