Hierarchical Builder with Reflection

I wrote a builder generator. It work also with derived classes.
Can use directly data members or methods, just by annotate them.
A short example:

class A
{
private:
[[=BuilderParam]]
int c_ = 10;

[[=BuilderMethod]]
void withBar(int bar) {
c_ = bar * 2;
}

public:
static auto builder() {
return makeBuilder<A>();
}
};

std::shared_ptr<A> a = A::builder()
.withBar(19)
.withC(20)
.build();
