编译的时候就是出错:
/data/Surface_matching/CloudViewer/src/CloudViewer.cpp:-1: error: undefined reference to `vtkSmartPointerBase::vtkSmartPointerBase()'

/data/Surface_matching/CloudViewer/src/CloudViewer.cpp:-1: error: undefined reference to `pcl::visualization::PCLVisualizer::createActorFromVTKDataSet(vtkSmartPointer const&, vtkSmartPointer&, bool)'
都是这种错误
