Web UI (HTML/CSS/JS Interface Widgets)

I’m getting clang++ duplicate symbol errors when trying to package a project on Ubuntu.

ld.lld: error: duplicate symbol: CefLogSeverityToWebBrowser(cef_log_severity_t)

Apparently defined in CEFWebInterfaceBrowserWindow.cpp and Module.WebBrowser.cpp.
Using the latest version of the plugin for 5.2 on Ubuntu 20.04.
I just put the plugin into my projects Plugins folder.
Did I miss anything? Do I need to built the plugin or the engine from source?
