I have to respectfully disagree. Cmake isn't super amazing and has some flaws and a less than ideal design and language, but it gets the job done. Autotools is more like something that was needed once in the 1980's when you had to support 300 different proprietary UNIX's and compilers / stdlib's weren't very standardized and had lots of bugs and warts, and now only exist because of inertia.
I too have to disagree. Cmake is crap compared to Autotools. It's makefiles don't work if the end user who does the compilation doesn't have cmake installed. Autotools doesn't have any runtime dependencies - that's a design goal that yes, still matters 2016.
