Libraries are installed into the directory $(libdir).

Before, the generated libraries were installed into the directory defined by: $(@PACKAGE@/libdir). In the default case, the installation path was "/usr/local/lib/wonrest". It required to add that path to the configuration file of "ld.so.conf". By installing the generated libraries into the default system path ('/usr/local/lib'), the user does not have to touch any other file.
