redo is pretty cool, but I ran into trouble with apenwarr's implementation (https://github.com/apenwarr/redo, see https://groups.google.com/d/msg/redo-list/GL5z8eEqT90/tk_vLZ...) with OS X Mavericks. I have no experience with the alternative implementation at https://github.com/gyepisam/redux, since it came out after I reimplemented the build system in question with CMake.

In general, I found CMake quite useable for my needs, and quite clean. It also required less build system code than redo. CMake fits quite nicely into a (C or C++) project which consists of many binaries and libraries which can depend on each other.
