Hello,

Have a look at
https://gist.github.com/afabri/17a675d3bbffaf351611921d8276d142

It compiles and runs on my machine (VC++).

jet gives better normals than pca

you still have to orient the normals. See in the gist.
Note that I pass the iterator returned by the orient function
to poisson.

Poisson needs Eigen. Have a look at 
examples/Poisson_surface_reconstruction/CMakeList.txt


  # Find Eigen3 (requires 3.1.0 or greater)
  find_package(Eigen3 3.1.0)
  if (EIGEN3_FOUND)
    include( ${EIGEN3_USE_FILE} )
  endif()

Best,

Andreas
