How to run qt application on embedded linux target

[Noushad]

Hi,

I am new to QT embedded development. I have windows desktop QT development knowledge.
I am trying to run examples on target board, but not working. Below are the details.

Board- Salvator-XS/ARM
OS Image Build - Yocto 3.9 and B2qt.
Display - Lilliput Touch

Board Connected to Display HDMI

root@salvator-x:/data/user/qt# ./PokyWidget -platform Wayland-EGL
Using Wayland-EGL
Using the 'xdg-shell-v6' shell integration
./PokyWidget: symbol lookup error: /usr/lib/libQt5Gui.so.5: undefined symbol: hb_font_set_ptem
root@salvator-x:/data/user/qt#

Below the Environment variables - Is there anything I am missing to run QT application on embedded target?
root@salvator-x:/data/user/qt# printenv
LD_LIBRARY_PATH=/usr/local/lib
OLDPWD=/data/user/qt/textinput
