Task #2699: unittest_runner returns the number of failed tests as exit status. However, the test framework treats exit status 3 as a skipped test. Moreover, since CMake doesn't provide a means to skip tests at run-time, exit status 3 is converted to 0. Hence, a run with three failing tests will inadvertently be flagged as 'passed'. This has been fixed by converting a non-zero exit status of unittest_runner to 1.
