"dynamic" linking uses LD_LIBRARY_PATH, not "static".  Static
linking is where you make the library part of the final executable.
It's not used a lot.  Dynamic linking requires the loader to link
the executable with the libraries it needs as you invoke the
executable.  This is how most things are done these days.

LD_LIBRARY_PATH is used on Linux/Unix machines to tell the "ld"
loader where to find libraries.  The more usual method for dynamic
linking is to tweak the "/etc/ld.so.conf" file (human-readable
text), then run "ldconfig" as root to create the "/etc/ld.so.cache"
(not human-readable) file that "ld" uses.  I sometimes have to add
a new directory to the file, such as "/usr/local/lib" which some
distributions forget at times, then run "ldconfig" so that the
loader can find libraries there.
