The INSTALL_NAME_DIR property of a target specifies how a dynamic library should
be found on OS X. If INSTALL_NAME_DIR is not specified the loader will search
relative to the standard search paths. If specified it should either be
an absolute path or relative path prefixed with either @executable_path,
@load_path, or @rpath. Specifying "lib" does not make sense here and
causes linking error as documented here:

This patch removes INSTALL_NAME_DIR everywhere it is set to "lib".
An alternate solution would be to set an absolute path like
"${CMAKE_INSTALL_PREFIX}/lib" or relative path like
"@executable_path/../lib". However, if there is not specific need for
specifying a path, it is probably best left unset.
