There are new errors for some of the extensions

@jcfr could this be related to the fixes of this topic? https://discourse.slicer.org/t/extension-build-failures

Looks like this issue has been resolved on today’s dashboard: http://slicer.cdash.org/buildSummary.php?buildid=1125383.

Hopefully it will go into history without explanation, and never return again!
