["Sebastien Loriot (GeometryFactory)" <>]

My guess is that you are not using cmake to generate your 
makefile/solution and you missed in the documentation this sentence:

"If Eigen 3.1 (or greater) is available and CGAL_EIGEN3_ENABLED is 
defined, an overload with Eigen_solver_traits<XXX> as default solver is
provided."

http://doc.cgal.org/latest/Surface_reconstruction_points_3/classCGAL_1_1Poisson__reconstruction__function.html#a5b01f27b151690449f33c9eb421f7c97

The solution is to either define CGAL_EIGEN3_ENABLED before including 
the reconstruction file or use the version taking explicitly the solver 
traits.

Sebastien.
