Ignore this warning.  This variable is not the permanent interface to turn on
this feature.

There are at least two problems:

(1) The DATA{} syntax only works inside itk_add_test.
(2) The path inside DATA{} should be a full path or relative to the CMakeLists.txt
    file containing it, not to the top of the data directory.
