I think it is a useful behavior to have. We use it within an enterprise environment to set a reasonable default, if the user hasn't specifically overridden it.  As one other commentor stated though, as a project developer (not CMake) you need to make this very obvious in case the user tries to figure out why something was installed somewhere (without the user telling it anything)!
