no matching function for call to ‘CesiumIonClient::Connection::Connection(CesiumAsync::AsyncSystem&, std::shared_ptr<osgEarth::Cesium::AssetAccessor>&, std::string)'

[virtuozo007]

osgEarth Version (required): the latest master version.

compiling with the latest Cesium-native lib.

From version 0.35.0, a parameter called "CesiumIonClient::ApplicationData&" was added in the constructor function of "Connection" in the "CesiumIonClient" module.

So, the "CesiumIon::refresh()" funtion in CesiumIon.cpp may need a modify as bellow, i guess:
Connection connection(Context::instance().asyncSystem, Context::instance().assetAccessor, getCesiumIonKey(), CesiumIonClient::ApplicationData());
