As expected, that will not work.  CMAKE_CFG_INTDIR can give the build tool a variable, which is expanded by the build tool, and you've effectively added another configuration directory level.
You could end up with a directory such as
/path/to/Debug/Debug/

That should work just fine.  CMAKE_CONFIGURATION_TYPES gives you a list of all possible configuration that can be chosen at build time.
