[CMake] How to establish hierarchical dependencies for CMake variables?

[SF Markus Elfring]

Hello,

The module "CMakeDependentOption" is provided for a while. Is it possible to
establish dependencies between other CMake variables (which are not "options")
in a similar way?
Can a string be automatically forwarded from one variable into parts at other
places during the build configuration?

Regards,
Markus
