Hi Marcus,

I tried to have a lib/CMakeLists.txt  and CMakeLists.txt with a same content like in ieee802-15-4 of Bastian, but it didn't work and now I had  this error after a modifications :

ImportError: /usr/local/lib/python2.7/dist-packages/ieee_868_915/_ieee_868_915_swig.so: undefined symbol: _ZN2gr12ieee_868_91511packet_sink4makeEv

You can get my project from a github :

Thank you a lot
