This is not a good example because make_foo did not return a pointer. It
returned an object by value. Therefore, when you do:

> auto foo_ptr = std::make_unique<Foo<int>>(external_library::make_foo());

The pointee is constructed fully in your control. You're creating a copy of
Foo<int> and saving that in a unique_ptr.

But note how Foo<int> can be copied. So are you sure you need unique_ptr in
the first place?
