The Ninja build tool

CMake Ninja files could use this issue[1] (I have a solution sketched out, but have not had time to implement it) being fixed to speed up quite a bit for projects with a large graph (when using targets as nodes). As for Makefiles, they have the same restriction in CMake, but apparently there is no way to do something similar. Have you done any further analysis on the performance pain points? Do you have repositories one could clone to get your benchmark tests so that we can use it ourselves?
