Executing start.sh from directory does nothing. When in terminal, this is what happens:

bash start.sh
Running Icewind Dale: Enhanced Edition
./IcewindDale: error while loading shared libraries: libjson.so.0: cannot open shared object file: No such file or directory

Cannot seem to find libjson.so.0 in my repos. I find plenty of package candidates with libjson, but none that have that exact match. Should I just install them all?
