ENH: CXX tests should not fail if VTK_DATA_ROOT is missing.
The vtkTestingInteractor was trying to run regression tests even if VTK_DATA_ROOT was not defined. Many Testing/Cxx CMakeLists.txt files tried to run tests that required input data, even though VTK_DATA_ROOT was not defined. Subsequent topics will address Tcl and Python tests.
