Adding to the search path

# https://stackoverflow.com/a/9631350/1697183
export LD_LIBRARY_PATH="/foo/bar${LD_LIBRARY_PATH:+:$LD_LIBRARY_PATH}"

This is more secure than plain appending, which can create empty components (e.g. a trailing ":") which are interpreted as "current directory" and lead to DLL search order hijacking.
