Compilation of Controller
-------------------------
Controller can be easily compiled with cmake. For that, follow the steps:
1. Create the build/ directory under controller/.
2. Run cmake .. under controller/build/

Note:
Controller relies on Hitmap for the creation and manipulation of data structures. Hitmap depends on MPI to work. The compilation toolchain of CMake will also compile Hitmap for you. However, Hitmap cannot be compiled if MPI is not found. In that case, you should specify the path to mpicc in the configuration file controller/extern/hitmap/config/make.platforms.def (MPICC variable).
