Include built libraries in Qt project.

[surajj4837]

I m using Linux 20.04 and built 3D library of Qt6.0.3 version. I referred following links to build the library:
https://www.kdab.com/getting-your-3d-ready-for-qt-6/#comment-153302
https://wiki.qt.io/Qt6_Add-on_src_package_build_using_Conan_package_manager

The build was successful.
The build directory is /home/suraj/Qt/Tools/Conan/build_dir
It has qt3d folder and along with it conanbuildinfo.pri.
I m using qmake build system, the second link says to include .pri file in the .pro file of project to include the library. Reference for including a generated pri file.

include(/home/suraj/Qt/Tools/Conan/build_dir/conanbuildinfo.pri)

QT += widgets 3dcore 3drender 3dinput 3dextras

Above include line was added in a sample folder but the build fails with following error:

:-1: error: Project ERROR: Unknown module(s) in QT: 3dcore 3drender 3dinput 3dextras

What am I missing?
