ctest matches warnings summary when using launchers
Using cmake 3.14.5 (sorry, what the latest Fedora gives me) I can see things like
<!-- Result of command -->
<Result>
<StdOut/>
<StdErr>[CTest: warning suppressed] XXXXXXXXXXXXXXXXXX.c:1:9: warning: macro name is a reserved identifier [-Wreserved-id-macro]
#define _DEFAULT_SOURCE
^
[CTest: warning matched] 1 warning generated.</StdErr>
<ExitCondition>0</ExitCondition>
</Result>
which CDash reports.
If I comment out the set(CTEST_USE_LAUNCHERS ON)
line from my ctest script that "1 warning generated" is (correctly) not counted as a warning.
