[Vv] Add HDF5 reading capability

[Jerome Lesaint]

Hi all,
I am trying to add an Nexus/HDF5 file reader in vv but am struggling with
the build configuration. The error I get at the end of the compilation is :

================

invocation)

make[1]: *** [vv/CMakeFiles/vv.dir/all] Error 2
===========

What I've done :
- added files common/rtkNexusHdf5ImageIO.cxx(and .h) and
common/rtkNexusHdf5ImageIOFactory.cxx( and .h)
- added #include <H5Cpp.h> in the common/rtkNexusHdf5ImageIO.h
- updated clitkIO.cxx and (root) CMakeLists.txt.

If I run `file /opt/homebrew/opt/hdf5/lib/libhdf5_cpp.dylib`, I get
`/opt/homebrew/opt/hdf5/lib/libhdf5_cpp.dylib: Mach-O 64-bit dynamically
linked shared library arm64`.

I guess the ITK - HDF5 installation interferes badly somewhere, but cannot
figure it out properly.
Any help would be much appreciated.
Thanks in advance,
Jerome
