I confirm that it works. (while the release branch still fetches the GCCXML cvs).

There is just a problem  with the 'make install'.  While CMAKE_INSTALL_PREFIX is
set and almost all the files  are installed into it,  FindWrapITK.cmake is tried
to be installed in privileged directory:

    -- Installing: /usr/share/cmake-2.8/Modules/FindWrapITK.cmake
