[CMake] how can I filter compiler warnings?

[Chuck Atkins]

These are really the kind of warnings that you want to disable with a
compiler flag but it will be specific for the given compiler.  Which
platforms do you see the warning on?  The error message looks like an xl
compiler warning.  Do you see it on other platforms as well?
