Qt find all dependencies of a project - qt

Question

I am creating a web browser with Qt 5.10.1 and I would like to export it with the Qt Installer Framework. I am looking for a way to know all the dependencies (libs, plugins...) my application has to export them with the binary file. I already used ldd for the libs but I don't know how to do for the plugins.
Thanks for your help.
When I use linuxdeployqt it seems to work but when I run the program I get
QML debugging is enabled. Only use this in a safe environment.
QApplication: invalid style override passed, ignoring it.
Could not find QtWebEngineProcess

You can use linuxdeployqt to find all used libraries and plugins. Qt does not ship anything like windeployqt for linux.
This Linux Deployment Tool, linuxdeployqt, takes an application as
input and makes it self-contained by copying in the resources that the
application uses (like libraries, graphics, and plugins) into a
bundle. The resulting bundle can be distributed as an AppDir or as an
AppImage to users, or can be put into cross-distribution packages.
If you are on Windows, you can use the windeployqt which comes with Qt.
