Personally I'd suggest Premake because it uses Lua instead of rolling its own scripting language. The world would be a better place if we could all agree on one scripting language for stuff like this so no one has to look up the syntax for things like creating arrays for every individual tool.
Feature-wise premake isn't entirely caught up to CMake but it has everything important. Also the premake files look a lot cleaner and more readable compared to cmake files.

It's called bloody "make". If Prolog is a language, so is make. Make is still a scripting language even if it's not boneheadedly sequential and imperative the way, say, Python is.
Make is simply not up to the job. It make writing correct build systems very difficult (hard to not under-specify dependencies). It does not support auto-generating code and then scanning it for extra build dependencies. It is a crappy tool and we should standardize on something better.
