    If you ever happen to want to link against installed libraries
    in a given directory, LIBDIR, you must either use libtool, and
    specify the full pathname of the library, or use the `-LLIBDIR'
    flag during linking and do at least one of the following:
    - add LIBDIR to the `LD_LIBRARY_PATH' environment variable
    during execution
    - add LIBDIR to the `LD_RUN_PATH' environment variable
    during linking
    - use the `-Wl,-rpath -Wl,LIBDIR' linker flag
    - have your system administrator add LIBDIR to `/etc/ld.so.conf'
    
    See any operating system documentation about shared libraries for
    more information, such as the ld(1) and ld.so(8) manual pages.
