If you run your tests as shell scripts, then you can set the exit code of
the shell script depending on any condition you like, and ctest will respond
to all non-zero exit codes as a failed test.  Note, setting up ctest this
way works cross-platform because there are shells (e.g., bash) available for
windows (or so I am told by those PLplot developers who run ctest for PLplot
on windows).
