There are several m4 macros that let you write autoconf detection for llvm. I recently needed to implement one. Have a look here: https://github.com/google/autofdo/blob/master/m4/ax_llvm.m4 Diego.

Building LLVM itself involves Cmake, but what's the best way to build a C++ program that needs to link with the LLVM libraries? If you're trying to optimise for making life as easy as possible for users and people creating binary packages, in the normal course of events, autotools is recommended. But the tutorial mentions running llvm-config to get things like library paths - does
