Qt Not Recognizing Qt/3D Libraries

Qt is not recognizing the Qt/3d i am using. I have QT Creator 4.7, and do not know if the problem is something i should include in my .pro file. I have QT 开发者_JAVA技巧+= opengl already. Some of what I am trying to #include are: QGLView, QGLBuilder, and QGLCube.

QGLView, QGLBuilder, QGLCube are introduced in QT 4.8. You need to update your QT library.
