Compile to .so file and install headers

KDE is asking us to be a proper library not just a submodule.

I did a quick hack that compiles a shared library, a few problems.

1) problem is that, marian is hardcoded to link to static MKL, so we have a rather large shared library, same with CUDA. (Although we could argue here that we do not want CUDA).

% strip libbergamot-translator.so 
% du -hcs libbergamot-translator.so 
31M     libbergamot-translator.so
31M     total
% ldd libbergamot-translator.so 
        linux-vdso.so.1 (0x00007ffc77d3b000)
        libtcmalloc_minimal.so.4 => /usr/lib/libtcmalloc_minimal.so.4 (0x00007f2868226000)
        libstdc++.so.6 => /usr/lib/libstdc++.so.6 (0x00007f2867e00000)
        libm.so.6 => /usr/lib/libm.so.6 (0x00007f286a338000)
        libgcc_s.so.1 => /usr/lib/libgcc_s.so.1 (0x00007f286a313000)
        libc.so.6 => /usr/lib/libc.so.6 (0x00007f2867a00000)
        /usr/lib64/ld-linux-x86-64.so.2 (0x00007f286a469000)

2) We really need to clean our headers if we want to be a proper library with headers to install.

Hello, There is a progress about this issue ? :)

Thanks a lot. Regards

Hi @Montel , We've looked and identified the necessary steps and it requires quite a big rewrite of the underlying build logic for marian and of our headers ;/ It's on the menu, but noone is working on it actively in the moment. PRs are welcome.

To be clear, we only need to install public headers. And part of the point of bergamot-translator is that it the public headers are relatively limited.
