Build in FreeBSD headless failed with `unresolved import wry::webview::WebviewExtUnix` and other misc error.

I'm attempting to build privaxy on freebsd and encountered these error:

It looks like it some gtk and UI related stuff (maybe tauri webview thing) but I'm not sure. Is privaxy GUI run using gtk or with webpage dashboard? If it is the latter case then can I just build the server since my freebsd env is headless.

Maybe relevant: #74, #13

Edit: Checking the github action on how to build server only looks like I missed some flag (especially adding --bin privaxy).
