Hi. I execute Slicer and get this error message:

```auto
mauro@mauro:~/Escritorio/Slicer-5.1.0-2022-09-19-linux-amd64$ ./Slicer
/home/mauro/Escritorio/Slicer-5.1.0-2022-09-19-linux-amd64/bin/SlicerApp-real: error while loading shared libraries: libitkhdf5_hl-shared-5.3.so.1: cannot open shared object file: No such file or directory

```

I got this same error after building Slicer this weekend on Arch. Copying the missing library from the build tree fixed the issue. There was a major ITK upgrade, the packaging script should perhaps be optimized.

Thanks for the report @mau_igna_06 and the suggested fix @chir.set 👍 I agree this sounds like a packaging script issue.

FWIW, Slicer-5.1.0-2022-09-19-macosx-amd64 runs for me on mac.

This patch allows to include the missing ITK library in the package :

```auto

   # HDF5 until ITK4. final, then it can be removed

```

Hopefully, it may get fixed in master.
