Note also that the -DCMAKE_INSTALL_PREFIX flag will change the location where the Python plugins are installed, so you may need to change the Python module search path via the PYTHONPATH environment variable. Often in physical science research, we end up with a hard problem of optimizing a function (called objective) that needs to satisfy a range of constraints – linear or non-linear equalities and inequalities. When you compile NLopt using the above commands, it will automatically compile plugins for both Matlab and GNU Octave (a free Matlab clone) if the latter programs are installed.
