   Linking LAMMPS statically or dynamically with other modules is making a

   In addition, as a special exception, the copyright holders of LAMMPS give
   you permission to combine LAMMPS with free software programs or libraries
   that are released under the GNU LGPL and with code included in the standard
   release of the "kim-api" under the CDDL (or modified versions of such code,
   with unchanged license). You may copy and distribute such a system following
   the terms of the GNU GPL for LAMMPS and the licenses of the other code
   concerned, provided that you include the source code of that other code
   when and as the GNU GPL requires distribution of source code.

   Note that people who make modified versions of LAMMPS are not obligated to
   grant this special exception for their modified versions; it is their choice
   whether to do so. The GNU General Public License gives permission to release
   a modified version without this exception; this exception also makes it
   possible to release a modified version which carries forward this exception.
