[CMake] CDash dashboard fail: Errors/Warning/Tests counts all zero?

[kent williams]

Consider if you will this dashboard page:

http://testing.psychiatry.uiowa.edu/CDash/index.php?project=BRAINS3&date=2010-09-13

I have several machines submitting Nightly builds to this dashboard
and they all appear to be generating non-empty XML files to upload,
and yet I'm getting blanks where I expect to see counts of
warnings/errors/etc.

Is this something other people have seen and it's a head-slappingly
simple problem to fix on either the client or server side?
