vst3editor error: 'auto' not allowed in lambda parameter

I am getting this error in a plug-in I am updating to VST3 SDK 3.6.9 and VSTGUI 4.5 (with Xcode 9 in High Sierra) :

/SDKs/VST_SDK/VST3_SDK/vstgui4/vstgui/plugin-bindings/vst3editor.cpp:65:9: error: ‘auto’ not allowed in lambda parameter
[] (auto) { gUpdateHandlerInit.get ()->triggerDeferedUpdates (); }, 1000 / 30);
^~~~
I have no idea what that means, let alone how to fix it, especially since it’s in the SDK, not my code. Anyone know the solution?

Thanks,
Howard

Looks like changing the standard library usage from c++11 to c++14 resolves this issue. I do not know yet if that will be compatible with my other SDKs (such as AAX, ARA and PACE).
