Who can tell me how to use MyGUI in NDK and Ogre for Android

[aaron_tree_2014]

I wrote these code in a project:
MyGUI::VectorWidgetPtr widgets = MyGUI::LayoutManager::getInstance().loadLayout("QuitButton.layout");
MyGUI::ButtonPtr button = GUISystem::getInstance().getGUI()->findWidget<MyGUI::Button>("QuitButton");
button->eventMouseButtonClick += MyGUI::newDelegate(this, &MyGui::quit);

But compiler throw an error: no match for 'operator+=' in 'button->MyGUI::Button::<anonymous>.MyGUI::TextBox::<anonymous>.MyGUI::Widget::<anonymous>.MyGUI::WidgetInput::eventMouseButtonClick += MyGUI::newDelegate [with T = MyGui](this, &MyGui::quit)'

Who can tell me how to deal with MyGUI.
