Nitpick: despite its name CMake doesn't really replace make (actually you can use it to generate Makefiles instead), it's more of a build configuration system like autotools.

As for criticisms of CMake, when I used it I thought it worked pretty well but I think its CMakeLists syntax is atrocious. Not that it's not an improvement over the autotools, but at least these ones have the excuse of being built on top of a mountain of legacy subsystems with various quirks.
