mysql - libmysqlclient error. No file (even though its there)

Trying to launch a program. I get the error as follows:

./theforgottenserver: error while loading shared libraries: libmysqlclient.so.16: cannot open shared object file: No such file or directory

I have libmysqlclient.so.15 in the /usr/lib64 directory. So the file is there, i even put it in the programs directory that I am trying to launch.
