I seem to be having issues with rack::app::CableWidget invocations in some VCV Rack ports.

```auto
    static void patchBetweenPorts(ModuleWidget* host,ModuleWidget* neighbour, PortWidget* output, PortWidget* input) {
        if (isPortPatched(input)) {
            WARN("can't patch to input that is already patched");
            return;
        }
        
        rack::app::CableWidget* cw = new rack::app::CableWidget;
        cw->inputPort = input;
        cw->outputPort = output;
	    cw->color = APP->scene->rack->getNextCableColor();
        cw->updateCable();
	    if (cw->isComplete())
            APP->scene->rack->addCable(cw);
    }

```

I see that CableWidget is defined in `metamodule-plugin-sdk/metamodule-rack-interface/include/app/CableWidget.hpp` - is there any reason why this symbol would be missing? It’s not redefined either by my current project

Looks like somehow that symbol got lost in the api symbols export. I’ll fix it, thanks for finding that.
