If you like the auto-tools (autoconf, automake, etc.) then you can
write some quick tests for the availability/usability of various VTK
headers, libs, etc. in your configure.ac file.  An example follows.

#===  configure.ac snippet

AC_MSG_CHECKING([for VTK header vtkCubeSource.h])

#include "vtkRenderWindowInteractor.h"
#include "vtkProperty.h"
#include "vtkCamera.h"
        ]],
        [[
  //  Cube
  //

  cube->SetCenter(2.0,0.0,0.0);
