You have an old HAS_VTK in your CMakeCache.txt file.  It is left from an
ancient FindVTK implementation that I recently removed from ITK.  I've
removed the code in Testing/Code/IO/CMakeLists.txt that adds this test.
Insight proper no longer uses VTK at all.  InsightApplications uses it for
the example applications.
