I'd like to generate a mesh on a circle, and all the boundary points are
required to sit exactly on it. So far, I can only see how to generate
meshed which are bounded by polygons [1]; here you insert linear contraints.

Any hints?

Cheers,

[1] http://doc.cgal.org/latest/Mesh_2/

Start by generating a 1D meshing of the circle matching the size criteria, create a 2D Constrained triangulation (starting by inserting the circle center to avoid performance issues) and then run the meshing.
This will works because all constrained edges in your mesh are already
Gabriel and also won't be refined since they match the size criteria.
