@Dr15Jones 
I tried to run it with the fragment below (*) instead, but then I get the "No data of type "GEMGeometry" with label..." error back. 

(*)
edm::ESHandle<GEMGeometry> h_gem;
  if (h_gem.isValid()) {
    setup.get<MuonGeometryRecord>().get(h_gem);
    lctBuilder_->setGEMGeometry(&*h_gem);
  }
