[vtk-developers] Dashboard hasn't shown "diff" images since CMake 2.8

[David Gobbi]

When a dashboard fails due to an image difference, errors like the
following are given instead of the actual diff image being shown:

File ../../../Testing/Temporary/TestSpiderPlotActor.png not found
File ../../../Testing/Temporary/TestSpiderPlotActor.diff.png not found

For example, see yesterday's dashboard:
http://www.cdash.org/CDash/testDetails.php?test=69080454&build=750165

When I run ctest-2.8 on my home machine, I see these same errors.
But with ctest-2.6, the image difference is correctly reported.

So ctest-2.8 is not finding or submitting the .png files that the tests produce.
Is this an error with ctest or an error within VTK?
