[CMake] What is the purpose of cmake's -N parameter?

[Steven Velez]

Well, sent that a little too soon.  I just realized that in my testing, I
wasn't specifying the source directory (which is an error) and when I do
"-N" does affect how "-L" behaves...

However, -L still leaves a lot of cache variables out (as does -LA), and I
would like to see the value of CMAKE_PROJECT_NAME.

Any tips?

Thanks,
Steven
