 To enable python support (Python[] function) in GetDP, follow [these instructions](https://gitlab.onelab.info/getdp/getdp/wikis/GetDP-compilation) (complex arithmetic) and add to the final cmake line:
 
 `-DENABLE_PYTHON=ON -DPYTHON_LIBRARY=/path/to/pythonlib -DPYTHON_INCLUDE_DIR=/path/to/pythoninclude`
 *  On Debian/Ubuntu systems, for python3.6 installed with apt-get,
