C++ resolve upper scope type at callsite [duplicate]

does anybody know why the following code snippet does not compile?

struct A
{
    struct Options
    {
        int a;
        int b;
    };

    A(const Options& opt) : opt_(opt) {}
    Options opt_;
};

template <typename T>
T build(const typename T::Options& options)
{
    return T(options);
}

int main()
{
    A::Options opt;
    auto test = build(opt);
}

GCC returns the following error: error: no matching function for call to 'build(A::Options&) although it seems (to me) like a matching function call is right there.

I can get the code to compile if I add a connection from Options back to A like so:

struct A
{
    struct Options
    {
        using Parent = A;
        int a;
        int b;
    };

    A(const Options& opt) : opt_(opt) {}
    Options opt_;
};

template <typename T>
auto build(const T& options)
{
    return typename T::Parent(options);
}

int main()
{
    A::Options opt;
    auto test = build(opt);
}

however, I'm making some modifications to existing framework where I would rather not add the A::Options::Parent hook in a bunch of places. Ideally, I would like there to be some way I could change the build function to get my desired behavior.

At the very least, this behavior is surprising to me. So any information is appreciated! Thank you.
