Error compiling structmember.h from Python2.7 library - c++

Question

I'm trying to create a Cmake file to compile an old C++ proyect, but when I run the make command I have this compile error:
In file included from /home/leontes/Dropbox/Siadex_Planner_ROS/planner/src/pyAPI.cpp:23:0:

And that is a System Library from Python...
I fixed the old make what was included with the proyect and it works fine, but with the new one no.
And the Cmakelist.txt that I'm building is this:
cmake_minimum_required(VERSION 2.8.3)
project(planner)

I'm missing something??
