Is the normal mode of operation to run 'cmake' followed by 'make'? Do
you not need to run 'cmake' ever again because 'make' is setup to
re-create the Makefiles from CMakeLists.txt as appropriate? Does that
work if you add new directories and such? Sorry for the noob questions
- I'm still trying to learn how you expect things to work.
