I've merged the topic to 'next' for testing, but without the CPack
or ExternalProject pieces.  Likely some more portability fixes
will be required after testing on the dashboard.  Once that is clean
I will add the other changes again on top of the revised topic.

For reference, that change is to ExternalProject with hunks like:

-  if(filename MATCHES "(\\.|=)(bz2|tar\\.gz|tgz|zip)$")
+  if(filename MATCHES "(\\.|=)(xz|bz2|tar\\.gz|tgz|zip)$")

Thanks.  Actually I think adding "xz" is incorrect anyway.  We
support compressed tarballs, not arbitrary compressed files.
Therefore the list should be

  7z|bz2|tar\\.gz|tar\\.xz|tgz|txz|zip

correct?
