After many tries, I found the way to build this application using a modified Docker container from https://github.com/Screenly/Anthias/tree/master/webview. My modification was to use balenalib/zynq-xz702:bookworm as the builder, instead of the image for Raspberry Pi.
I have already installed QT5 packages in this system.

Now, when I try to run application on the target system (Zynq-7000 with Debian 12) I got an error:

QtWebEngine::initialize() called with QCoreApplication object already created and should be call before. This is depreciated and may fail in the future.
This plugin does not support createPlatformOpenGLContext!
Attribute Qt::AA_ShareOpenGLContexts must be set before QCoreApplication is created.

Looks like I have to configure (or fix) some environment variables, but I'm new to QT and really don't know how to debug this issue.
Please help me make it work.
