+	    HACK(mihe): This is to work around a bug in Godot 4.3-beta1, where it treats Framework
+	    bundles the same as XCFramework bundles, and expects there to be an `AvailableLibraries`
+	    entry, which is really only a thing in XCFramework bundles. Note that we also lie about the
+	    binary path having a `.dylib` extension in order for Godot to correctly identify this as a
+	    dynamically linked bundle.
