Yes, that looks like a very useful switch. I've never seen it before - but 
that's probably because I wrote the ctest stuff in cmake 2.6 times.

Isn't cmake able to figure out by itself that it's running in ctest submission 
mode? Then I'd consider to enable launchers per default for this. I can't see 
a reason why you don't want to have it.

Becaue cmake first matches the error regexps and then discards all candidates 
that match CTEST_CUSTOM_ERROR_EXCEPTION. Since almost all error messages match 
this regexp, it would suppress everything I want to have reported. Or did I 
misunderstand this?
