[Libqtlua-list] How qtlua register Qt's classes?

[Li]

I just compile it in Windows 7
QtLua 2.0 (using Qt 5.4.1 and Lua 5.1.4)

I use cmake-gui to configure this project

>>window=qt.new_qobject(qt.meta.QWidget)

It give me an error

error: [string ""]:1: QtLua::ValueBase:The value contains a null 'QtLua::UserData' reference.

>>list(qt.meta)

It says that qt.meta has no QWidget and any other QObject derived classes.

However, in my Ubuntu, it does.

I just check tools/qtlua/qtlua.cc

found that it doesn't register any classes.

I want to know where can I find those code for register work.

Thanks
