[CMake] Return code from CMake script

[David Cole]

Presently, there is no way to do that. It would be a reasonable feature
request to add an "EXIT_STATUS" or "EXIT_CODE" parameter to the message
command to enable this functionality.

As an alternative (workaround), perhaps you could write the status value
into a file that you inspect after CMake returns?


HTH,
David
