All a new connect from SIGNAL to lambda, because Qt5 signals/slots syntax doesn't work when signal in dll.

This syntax:

QObject::connect(quit, &Sender:clicked, this, &Receiver::close)

will fail when called connect in a dll, it report "QObject::connect: signal not found in...",
so when i connect to a lambda use the new Qt5 signals/slots syntax in dll will failed.
But when called in exe, it is ok.

The old syntax:

QObject::connect(quit, SIGNAL(clicked()), this, SLOT(close()));

works alwasy fine.

So I hope you can let us call by the syntax:
QObject::connect(quit, SIGNAL(clicked()), this, &Receiver::close);
Then I can use lambda in dll.
Thanks!
