I was thinking about this issue recently. http://thread.gmane.org/gmane.comp.programming.tools.cmake.devel/6106 It's becoming conventional to use a namespace like NS:: for imported targets. Would it be possible to assume that if linking to something which has double colons, then it must be an imported target, and if we can't find such an imported target, to report an error at generate time? That would also be an incentive to use the convention of using :: in imported targets, and we could document it as recommended. For makefile generators and xcode it is not possible to use create non-imported targets in a buildsystem. On Windows it doesn't seem to be possible either (the : is mistaken for a drive delimiter). It does currently work with Ninja though, so a policy may be needed if it's a workable solution.
