 To install the system dependencies, it is possible to use [Homebrew](http://brew.sh/):
 ```

+brew install ace bash-completion boost cmake eigen gsl ipopt jpeg libedit opencv pkg-config portaudio qt@5 sqlite swig tinyxml libmatio irrlicht spdlog

 Since Qt5 is not symlinked in `/usr/local` by default in the homebrew formula, `Qt5_DIR` needs to be properly set to make sure that CMake-based projects are able to find Qt5.
