The GetProperty method is now just accessing contained data, meaning it can be implemented in cmState. Remove the cmMakefile context from the signature as a result and remove the overload with the same signature. Add a GetComputedProperty to cmTarget so that templates can be properly instantiated. Otherwise the Commands would need to be able to reach the specializations which are currently in cmTarget.cxx. As a side-effect, the CMP0026 warning now gives a backtrace to the target when issued from a generator expression.
