[CMake] making the build fail

[David Cole]

Not directly... Not with existing ctest.

But after the ctest_coverage call, there should be a file in your
binary tree called something like "Testing/20120109-0100/Coverage.xml"
-- it is the xml file that will be submitted to CDash reporting what
files have what percent coverage. Near the bottom of that file, there
will be a line like

"<PercentCoverage>74.83</PercentCoverage>"

representing the total overall coverage value.

You could extract that number from there if you want to trigger some
action based on its value.

On the other hand, you can (as a project admin) define what percentage
coverage constitutes "failed coverage" for a project on the CDash
dashboard. Then, when the coverage is below that threshold, it will
show up as yellow to indicate "failed coverage result".


HTH,
David
