[CMake] Return code from CMake script

[Kent Williams]

If CMake is running a script via -P, doesn't it return a non-zero
status if there's any error?

I'd think it would be sufficient to run to the end of the script if
everything works fine, but have something like

if(something_went_wrong)
  message(FATAL_ERROR "¡OH NO! ¡SUCEDIO ALGO TERRIBLE!!!")
endif(something_went_wrong)
