If the application is to be cleanly installed to a standard linux distribution, then you should either install the supporting shared libraries into a standard location (/usr/lib), or you should add the libraries location to the ld.so config, by create an /etc/ld.so.conf.d/myprogram.conf file containing the name of the directory the libraries are in.

If the installation is temporary or more ad-hoc, then a script to set the LD_LIBRARY_PATH is suitable.
