However, if there are libraries in directories other than these, they need to be added to the /etc/ld.so.conf file in order for the dynamic loader to find them. Some directories that are commonly known to contain additional libraries are /usr/local/lib, /usr/local/lib64, /opt/lib, and /opt/lib64, so add those directories to the dynamic loader's search path.
