Hi,

I guess that you need to link with QGLViewer library.

Check Surface_reconstruction_points_3 demo's CMakeLists.txt. You need:

  find_package(OpenGL)
  find_package(QGLViewer )
  ...
  include_directories ( ${QGLVIEWER_INCLUDE_DIR} )
  ...
  target_link_libraries( Point_set_demo ${QGLVIEWER_LIBRARIES} 
${OPENGL_gl_LIBRARY} ${OPENGL_glu_LIBRARY} )

Best regards,
Laurent Saboret
