Do we modify our included libraries?

Specifically, can I use system versions of these in a build and expect ok results (ignoring CRAN issues):

  • Eigen
  • Boost

I think we still string print statements from CVODES but I’m not sure about anything else.

There are arguments to stan_model for the Eigen and Boost libraries, but CVODES is built into the StanHeaders shared object, so there is probably no avoiding that.
