[Cdash] Problem with cdash, subprojects and CTEST_USE_LAUNCHERS=TRUE ?

Are the subprojects built via ExternalProject_Add calls?

If so, and the default make command contains the "-i" flag, then
perhaps make will return no error even if there are build errors. And
if the make does not return an error, then ctest with launchers will
not report an error. (Whereas without launchers, it will simply scrape
the output looking for matches to the known set of error regular

I'm pretty sure this is the case that we've seen before with a
subproject-based dashboard using a Super Build ExternalProject

The solution is to either avoid using the launchers for such project
dashboards, or come up with a way to make "make" return errors when
there are build errors.

If I am off base here, perhaps you could give steps to repro so I can
take a closer look?

Thx, (and hope this helps),
David C.
