Hello,
I’m a developer of the plugin-ARTn software (pARTn documentation), which relies on the plugin package/command of lammps.
We recently saw that the option for installing the package plugin was removed from Makefile, and were wondering if that signals any special status for the future of the package (removal)?
No, it only signals that we are favoring building LAMMPS with CMake over the traditional GNU make process and all packages that required special (manual) steps in building LAMMPS have since been removed from the traditional build process. This is also documented and there will be a corresponding message, if you try to install such a package with the traditional build process.
