The -Wdev/-Wno-dev options have always been for all messages
output by any part of CMake. This needs to be preserved/corrected.
Okay, I've fixed the change to cmake::PrintMessagePreamble, so that
it'll stop warning or error dev or deprecated messages getting printed
out when the relevant CMake variables have been set. I just need to add
some more test cases to cover this and I'll submit a patch.
Likely yes. This may require sweeping changes to address. We're
too close to the freeze for 3.4 to do this now. Perhaps we should
simply remove -Werr-dev for now.
Yes the -Werr-dev, -Wno-err-dev, -Werr-deprectated and
-Wno-err-deprecated may be trickier than expected to get behaving as
intended. I'll try and get a better idea of the users of IssueMessage
and see if some ideas come to mind. Removing them would be fair enough
at this point, better to not include them than to include broken
functionality I'm sure. Do new features, such as -Werr-dev, have to be
sent by October 1st is it?
Cheers,
Michael
