[CMake] Making Relocatable Binaries (AIX, SunOS, HPUX testers wanted)

[Mathieu Malaterre]

If you do not have subversion on your system, you can get a tarball
using for example wget:

 $ wget --no-check-certificate
"https://gdcm.svn.sf.net/viewvc/gdcm/Sandbox/RelocatableModule.tar.gz?view=tar"

Thanks,
