Installing Qt on Yocto

Question

I am working on a project contains, “Renesis R-Car H2 board” with Yocto installed in it. I am trying to find a proper way to install Qt in Yocto. Actually my application is running very slow in Yocto. I think it’s because of wrong Qt configuration. It would be very much appreciated if someone could help me to solve this problem.

Refer to 'Adding Qt5 in Yocto image'

If you try to run example applications, after successful build you must be able to run Qt5 examples on target:

export LD_PRELOAD=/usr/lib/libEGL.so
export XDG_RUNTIME_DIR=/run/user/root
export QT_QPA_PLATFORM=wayland-egl
/usr/share/qt5/examples/opengl/cube/cube
