Bug#1086673: libopenmpi3t64: /usr/lib/x86_64-linux-gnu/libmpi_cxx.so.* is missing

[Florian Foinant-Willig]

Package: libopenmpi3t64
Version: 5.0.5-3
Severity: important

Dear Maintainer,

when trying to compile a libmpi dependent application, I'm facing a
"/usr/bin/ld: cannot find -lmpi_cxx" error.
Looking into the libopenmpi3t64 amd64 package file list
<https://packages.debian.org/sid/amd64/libopenmpi3t64/filelist> I don't 
see any
/usr/lib/x86_64-linux-gnu/libmpi_cxx.so.*
This file was present in the trixie package (4.1.6-13.3) and the i386 
sid one
so I think it's a mistake with the 5.0.5-3 package compilation.

The required file can not be found in any other amd64 sid package:
<https://packages.debian.org/search?suite=sid&arch=any&mode=filename&searchon=contents&keywords=libmpi_cxx>

Regards,
Florian
