Error when ran <cmake -G"Unix Makefiles">

[zhangyingjie7]

Hi,
I follow the instruction of libOTe, and it has passed my test ./frontend_libOTe -simplest-asm
For Ivory-Runtime, I run cd Ivory-Runtime/thirdparty/linux, and bash ./ntl.get.
but when I continue to run cmake -G"Unix Makefiles", an error occured as follow:

CMake Warning:
  No source or binary directory provided.  Both will be assumed to be the
  same as the current working directory, but note that this warning will
  become a fatal error in future CMake releases.


CMake Error at ivory/CMakeLists.txt:45 (message):
  Failed to find libOTe at libOTe_LIB-NOTFOUND
