CMake support

It would be nice to have CMake support to install this plugin, as it is the recommended option according to docs to build LAMMPS.

would this be a good example?

I guess it is. I think that the problem is that this project is missing a CMakeLists.txt file, but I'm new to LAMMPS and I don't have the technical knowledge to create it.

I agree that this needs to be done and I will see how to add cmake support in the near future. I was planning to remove unnecessary things from the fix first and use that as the basis.
