Qt Creator中Qt5.9.2使用QVTKWidget报错LNK2019和 LNK2001

[峰行无双]

#include "mainwindow.h"
#include "ui_mainwindow.h"

MainWindow::MainWindow(QWidget *parent) :
QMainWindow(parent),
ui(new Ui::MainWindow)
{
ui->setupUi(this);
this->setWindowTitle("PointCloud View");
cloud.reset(new pcl::PointCloud<pcl::PointXYZ>);
viewer.reset(new pcl::visualization::PCLVisualizer ("viewer",false));
ui->qvtkWidget->SetRenderWindow(viewer->getRenderWindow());
viewer->setupInteractor(ui->qvtkWidget->GetInteractor(),ui->qvtkWidget->GetRenderWindow());
ui->qvtkWidget->update();
}
Qt Creator构建项目时出现下面的错误，怎么解决，有大神能指导一下吗？
