[Insight-developers] ThirdParty warning suppressions, an experiment

[Bill Lorensen]

Folks,

Over the past moths I have been complaining about third party
packages, mainly, gdcm, that are generating warnings. There has been
little if any progress in fixing the third party warnings. We have
been assured that gdcm will be cleaner once we update to the new
release. However, for the time being, I propose to suppress all third
party warnings. If nothing else, it will make it easy for us to clean
itk. It will also show haw bad these third part packages are with
regard to warnings.

Today's itk4 nightly dashboard shows 873 warnings (so far).

I'll be submitting a gerrit patch to suppress the third party
warnings. If approved, I'll merge it.

Bill
