include(HandleLLVMOptions) is what adds all the non-target specific compile flags (including /W4), which conflicts with the /w flag used for duktape.

non-target specific compile flags

Oh... I hate these. /w is private even.

I think there's a way to use LLVM with this module but I don't remember how.

I guess we can fix this simply by finding LLVM last though.

I tried importing LLVM after all other dependencies but the error is still there.

I think the only solution here is to find another way to consume LLVM without these scripts that define global requirements.
