cmake-buildsystem
-----------------
To use the cmake build system instead of the make-driven one, do:
```
cmake /path/to/lammps/source/cmake
```
(please note the cmake directory as the very end)
To enable package, e.g. GPU do
```
cmake /path/to/lammps/source/cmake -DENABLE_GPU=ON
```
cmake has many many options, do get an overview use the curses-based cmake interface, ccmake:
```
ccmake /path/to/lammps/source/cmake
```
(Don't forget to press "g" for generate once you are done with configuring)

you have to make certain to use the same MPI library (or the STUBS

-DLAMMPS_BIGBIG, -DLAMMPS_SMALLBIG, or -DLAMMPS_SMALLSMALL define.

<p>Sets the energy exchange mechansim from the finite elements to the atoms, managed through a control algorithm. Rescale computes a scale factor for each atom to match the finite element temperature. Hoover is a Gaussian least-constraint isokinetic thermostat enforces that the nodal restricted atomic temperature matches the finite element temperature. Flux is a similar mode, but rather adds energy to the atoms based on conservation of energy. Hoover and flux allows the prescription of sources or fixed temperatures on the atoms. </p>
