How to write C++ extension with C++ for QML view?

[useryy2]

I just write some files according to this

I compile it successfully and got 2 files in lib folder

But I can't use this extension in my qml files.

I have my file structure on my disk like this,
1) project.qml, 2)"content" folder
In "content folder": 1) others.qml 2) plug-in folder

I've installed the QTSDK only.

So where the qml will find my the plugin files which is generated in my lib. Or where shall I place them?
Or, where the qt quick will find the library which contains element info?
