Hello @rakesh3,

I hope you are doing well.

while building the qt6 project

Please make sure to use Linux LF5.15.5_1.0.0 or a later version.
It is recommended to use the latest BSP.

In order to include Qtwebengine in the image, put the following in local.conf or in the image recipe.
IMAGE_INSTALL:append = " packagegroup-qt6-webengine"

Also, ensure to build imx-image-full image because It builds an open-source Qt 6 image with Machine Learning features.

For more details, please refer to section 5.6.6 Qt 6 and QtWebEngine browsers in the Yocto user guide.
https://www.nxp.com/docs/en/user-guide/IMX_YOCTO_PROJECT_USERS_GUIDE.pdf

I hope it helps!

Thanks & Regards,
Sanket Parekh
