Xdmf3 drops libraries to the build directory root on Windows
Xdmf3 is dropping its .dll and .lib files to the root of the build tree on Windows. The .dll needs to go to the bin subdirectory and the .lib should go to the lib directory. I looked at the logic in the Xdmf3 code and I'm not sure enough to go and just remove the wonky MSVC10-guarded blocks (which I don't think should be required at all).
This is causing all of the Python tests to fail on the nemesis buildbot (since VTK tries to import all modules in its package's __init__.py file.
