De-serialize pickled files

Hi,

I am trying to find a way to open my .pkl files in C++. One way to do this is to use the PicklingTools, however, there is a conflict when building with LibTorch. I see the following error:

 undefined reference to `OC::MakeVector(std::string const&, unsigned long, char const*, unsigned long)'

I believe PicklingTools uses OpenContainers, is there a known fix for this? Or some other recommended option to deserialize pickled files?

Thanks!
