title: migrating a project from vtk5.10 to vtk 7.1 - missing headers
body: <p>I am trying to migrate a project with Qt4.8.0 and vtk 5.10 to an updated version with Qt5.7 and vtk7.1 (in Visual Studio 2013). </p>
  
  <p>I found out that many vtk files have changed through different versions. Is there an easy way to do the migration? The great problem I have so far is with the vtkSource header file. </p>
  
  <p>Thank you in advance. </p>
