Problem building CM12.1 with libmdmdetect

I started building a CM12.1 ROM by myself following the steps found in CM building site for the OPO.

The thing is that I get this error

Code:

---

No rule to make target «libmdmdetect»,
needed by «/root/android/system/out/target/product/bacon/obj/lib/libqmi.so»

---

I've read something about getting libmdmdetect from another device (from shamu, for example), but I don't know how and I don't know where to put it. I think the failure is not libqmi.so, since it needs the other one.

I'm a noob making my first steps on making ROMs by myself. Any help would be helpful.
