LLVMConfig.cmake in LLVM package

In the basic example of setting LLVM development environment here:
http://llvm.org/docs/CMake.html#embedding-llvm-in-your-project
it is mentioned "${LLVM_ROOT}/share/llvm/cmake" directory which is used to `include` a file LLVMConfig.cmake (code: include(LLVMConfig)).

I just can't see this fragment of LLVM directory tree (${LLVM_ROOT}/share/llvm/cmake) and the file LLVMConfig.cmake in Ubuntu distribution. Would you please point me out what do I miss?
