As specified by FHS:

   /usr/lib includes object files, libraries, and internal binaries that
   are not intended to be executed directly by users or shell scripts.

   Applications may use a single subdirectory under /usr/lib. If an
   application uses a subdirectory, all architecture-dependent data
   exclusively used by the application must be placed within that
   subdirectory.
