I can get Ipopt's version from an executable via the command line: ipopt --version. However, I would like to get the version from the c++ interface, which does not use the executable. Is this possible?
For context, I have installed Ipopt following the standard instructions (on the GitHub repo) and am running the cpp example included:
https://github.com/coin-or/Ipopt/blob/stable/3.14/examples/Cpp_example/cpp_example.cpp
on Ubuntu 18.04.
My end goal is to get the Ipopt version used by CyIpopt, which links against libipopt.so similarly to the c++ interface, so I thought that this was a good first step.
The version is defined in IpoptConfig.h as IPOPT_VERSION.
