 ### Dependencies
-BIORBD relies on several libraries (namely eigen ([http://eigen.tuxfamily.org]) or CasADi ([https://web.casadi.org/]), rbdl-casadi (https://github.com/pyomeca/rbdl-casadi), tinyxml2(https://github.com/leethomason/tinyxml2) and Ipopt (https://github.com/coin-or/Ipopt)) that one must install prior to compiling. Fortunately, all these dependencies are also hosted on the *conda-forge* channel of Anaconda or will automatically be compiled when building BIORBD. Therefore the following command will install everything you need to compile BIORBD:
