Thank you, that looks interesting too. In addition I like Lua because is much more light weighted than python and being embedded is nice to reduce dependencies.

The only problem I see is fragmentation. People are already considering cmake as the de facto standard despite all its flaws. If the cmake alternatives are too fragmented it will play in favor of cmake.

On the other side projects like xmake are interesting propositions. I will have a look at it in any case, thank you.
