Compilation error using rest and rime together in Cooja - c

Question

I am trying to create a ContikiOS firmware that acts as a gateway using Rime and REST. The gateway must communicate to other motes with the Rime mesh, and can communicate to the outside via a REST API.
The following code is a combination from two default Contiki examples (rest-example/rest-server-example.c and rime/example-mesh.c). Therefore I include "rest.h", "net/rime.h", "net/rime/mesh.h".
The problem is when I try to compile this firmware using following makefile, the rime files don't get included into obj_sky and any Rime functions I use in the firmware get an 'undefined reference' error. However when I remove the lines in the makefile and any code referring to REST in the firmware code, it does compile (and adds the rime files to obj_sky).
Would anyone have an idea why rime does not get added after adding the rest-http app and what I can do to have it compile?
Thank you
Code

I am using Sky motes to compile the code in Cooja.
