How can I enable QtCanvas3D plugins
-
As the title says, I don't have QtCanvas3D module when I want to use it

Now I have download QtCanvas3D Source Code from https://github.com/qt/qtcanvas3d and I have compiled it with my computer.
I get these files

I guess that it may lack of such as qmldir file or other plugin configure files, but I don't know how to do.

Oh, I have found the solution on http://doc.qt.io/qt-5/qtqml-modules-topic.html
I'd like to follow this doc. And it seems helpful
