如果按照官方指導的步驟在Mac上成功編譯安裝了VTK，那么下一步如何使用VTK庫呢？用Cmake是一種簡單的途徑，那么如何寫CMakeLists.txt呢，參考官方的例子
必須熟悉新版本的vtk的cmake文件命令，比如老版本的例子中的vtk_module_config和include(${VTK_USE_FILE})在新版8.90.0中都不適用了。
調(diào)用vtk的源代碼: 繪制一個圓錐

#include "vtkPolyDataMapper.h"
#include "vtkRenderWindow.h"

vtkConeSource *cone = vtkConeSource::New();
cone->SetHeight( 3.0 );
cone->SetRadius( 1.0 );
cone->SetResolution( 10 );
vtkPolyDataMapper *coneMapper = vtkPolyDataMapper::New();
coneMapper->SetInputConnection( cone->GetOutputPort() );
vtkActor *coneActor = vtkActor::New();
coneActor->SetMapper( coneMapper );
vtkRenderer *ren1= vtkRenderer::New();
ren1->AddActor( coneActor );
ren1->SetBackground( 0.1, 0.2, 0.4 );
vtkRenderWindow *renWin = vtkRenderWindow::New();
renWin->AddRenderer( ren1 );
renWin->SetSize( 300, 300 );
vtkSmartPointer<vtkRenderWindowInteractor> renderWindowInteractor =
vtkSmartPointer<vtkRenderWindowInteractor>::New();
renderWindowInteractor->SetRenderWindow(renWin);
renWin->Render();
ren1->GetActiveCamera()->Azimuth( 1 );
renderWindowInteractor->Start();
cone->Delete();
coneMapper->Delete();
coneActor->Delete();
ren1->Delete();
renWin->Delete();
return 0;

make之后會生成一個名為cone.app的Mac程序包，直接雙擊就可以運行。.app的生成是由MACOSX_BUNDLE變量控制的
