Cannot generate bindings to nlopt or ipopt

[psigen]

We are currently suppressing the following solvers:

  'dart::optimizer::IpoptSolver': null
  'dart::optimizer::NloptSolver': null
  'dart::optimizer::DartTNLP': null

This means that running chimera without these optional components causes parsing errors (since these classes are not included if the components are not present.

This issue arose in #20 (comment)

[jslee02]

Would commenting the lines of the solvers resolve the parsing errors when they are not installed?

dart-optimizer-ipopt-dev is not available on trusty. Could we make the Chimera configuration file to be configured in cmake time to disable ipopt and other optional components when they are not installed (like configuring chimera.yml.in to chimera.yml)?

[psigen]

Yes, I think that would be possible. There is a CMake macro for using Chimera, so we could add a configure_file step as a dependency to that macro. If not, another option would be passing the same information as command line flags.
