Compile C dependency

Hi:
I'm interesting for this project. But when I try to build, the blscgo/bls.go need releated C header file and the lib for "bls_if.h"
I try to build the project "bn" whilch is belong to "dfinity", but this C project is not suit to "random-beacon".
So could your tell me where to get the dependency?
I don't wanna just use the docker. 
Thanks!
