I may be nitpicking, but I disagree that there is a significant fundamental 
difference between Superbuild and the others. All are scripts that start 
separate processes for all they do, including building the projects 
(ExternalProject runs a separate 'cmake' command using execute_process).

They are all "separate scripts", written in Perl, Ruby, and CMake
