Issue with building source

I'm getting kind of the same thing, by that I mean errors regarding LLVM stuff when trying to compile on linux with cmake

Code:

nothing@nothing ~/Documents/ $ cd rpcs3 && cmake CMakeLists.txt && make && cd ../

  Add the installation prefix of "LLVM" to CMAKE_PREFIX_PATH or set
  "LLVM_DIR" to a directory containing one of the above files.  If "LLVM"
  provides a separate development package or SDK, be sure it has been
  installed.
