If you use a shared library the operating system must know where to find
it. LD_LIBRARY_PATH is one way of telling where to search.

You can link glpsol statically with all involved libraries. Then you
don't have to care about library locations anymore.

This is what Domingo suggested.

You can use the ldd command to find all linked shared libraries.
