This library from google is used everywhere in robotics, so it's hardly some backwater little side project.
So does c++ autodiff

casadi

4 1,549 9.3 C++

CasADi is a symbolic framework for numeric optimization implementing automatic differentiation in forward and reverse modes on sparse matrix-valued computational graphs. It supports self-contained C-code generation and interfaces state-of-the-art codes such as SUNDIALS, IPOPT etc. It can be used from C++, Python or Matlab/Octave.
