Summary:                    ExternalProject module needs small patch to allow
unpacking of *.tar.xz files
Description: 
The CMake logic in ExternalProject.cmake does tests for filename patterns which
currently do not contain the pattern for *.tar.xz.  The attached patch fixes
this issue so that ExternalProject_Add correctly unpacks *.tar.xz files on
Linux.  


Steps to Reproduce: 
Use ExternalProject_Add to attempt to unpack a *.tar.xz tarball on Linux.

Additional Information: 
Note there is a related fix (consisting of importing the latest libarchive
source code into CMake) in the works that should allow "cmake -E tar xfz
*.tar.xz" to work properly on MSYS.  When that fix is combined with the present
one the result will be that ExternalProject_Add correctly unpacks *.tar.xz files
on MSYS (as well as Linux).
