Note you can add an rpath to avoid having to modify LD_LIBRARY_PATH;
rpath is just better for this kind of thing.  As a general rule of
thumb, if you're installing somewhere outside of the target system's
/etc/ld.so.conf, add an rpath.  And for this purpose ignore e.g.
Fedora's broken tendency to put private libraries in
/etc/ld.so.conf.d.
