Feature/vtk7 compatibility
The aim of this branch is to provide transparent VTK7 support for the develop branch:
- if you have VTK6 installed on your machine, everything should work like before
- if you have VTK7 installed on your machine, everything should work too, with a few more disabled test
Some tests need to be disabled when using VTK7 because as for now we cannot manage multiple version of expected output files (and therefore files that are saved using VTK7 differ from the expected files that were saved using VTK6)
Directory sdk/cmake/ctest/testdatavtk7 contains the expected files that were saved using VTK7.
When CamiTK develop move to VTK7, just move the files of this directory to their respective location. All tests will then pass.
