title: CMake VTK_DIR-NOTFOUND
body: <p>VTK_DIR-NOTFOUND is returned when using CMake. I am using CMake GUI and, as other path errors, I can point then to proper path. However, for VTK doesn't work. I am pointing to directory where VTConfig.cmake file and others are. Also tried with all of other VTK dirs but without any sucess. I am using Visual Studio 12 2013 Win 64 configuration for generation but tried with 2010 too.</p>
