Fix boost requirements and deps for flesnet ipc in cmake files

Add missing iostreams and system requirement and dependency

Add special case for macosx
When using libboost_iostreams below 1.80.0 libzstd is linked explicitly
but not found even if installed in /usr/local/lib so we need to add this
path to the target properties.
