Where are these header files (noticed while building OpenVSP)?

1. "eli/geom/surface/piecewise_cubic_spline_skinning_surface_creator.hpp"
2. "eli/geom/intersect/specified_distance_curve.hpp"
3. "eli/geom/intersect/specified_thickness_curve.hpp"
4. "eli/geom/intersect/minimum_dimension_curve.hpp"
5. "eli/geom/surface/piecewise_multicap_surface_creator.hpp"
6. "eli/geom/intersect/distance_angle_surface.hpp"

In order to build OpenVSP, you need to use either the bundled version of Code-Eli, or (if you're building a standalone version) you need to be using the 'right' one. Today that is the version in https://github.com/ramcdona/Code-Eli/tree/master .
