[vtk-developers] Testing utilities

[Shepherd, Jason F]

Hey guys,

I've noticed that there are (seemingly) two ways of getting to the VTKData directory from a test file:

vtkTestUtilities::ExpandDataFileName(...)
and
vtkTesting::GetDataRoot()

The first one looks for a command line argument, then for a VTK_DATA_ROOT environment variable, and failing those uses "../../../../VTKData".
The second option looks for a command line argument, then for a VTK_DATA_ROOT environment variable, then a CMAKE variable (VTK_DATA_ROOT, again), and failing those applies "../../../../VTKData".

Is there a reason for not checking for the CMAKE variable in ExpandDataFileName() ?
