This directory contains libraries that can be linked to when building LAMMPS, if particular packages are included in the LAMMPS build.

Most of these directories contain code for the library; some contain a Makefile.lammps file that points to where the library is installed elsewhere on your system.

In either case, the library itself must be installed and/or built first, so that the appropriate library files exist for LAMMPS to link against.

Each library directory contains a README with additional info about how to acquire and/or build the library. This may require you to edit one of the provided Makefiles to make it suitable for your machine.
