If you are using C++17, there is std::optional designed just for this situation. You could return a raw pointer (assuming the collection outlives the use of its objects), a unique_ptr (construct a new object) or shared_ptr (and store the Packages as shared_ptr objects).

Another option is to pass a non-const reference to a Package and have the method return a bool indicating success or failure.

As has been pointed out, you could also return an empty object. This is the only choice if your design is constrained to return just an instance.
