Notice that nimble now supports tasks, which are custom command, scriptable with nimscript. This should be extensible enough to cover your needs.
Nake is a build tool - I have never used it, since I find that build tools need to be coupled to a package manager to be useful - there is no way to build anything non trivial without making use of dependencies, and then your build tool must be in some way aware of what dependencies are available and where. This is why I think that coupling package managers and build tools makes sense, but I know people whose opinions differ
