I'm trying to build Cxx: "Pkg.build("Cxx")".But something went wrong.Here's the infomation:

I know the mathcine cannot find "LLVM", But I'm primary in Programming.I don't know what the LLVM is. I also tried Pkg.build("LLVM"), but after doing this. It's still wrong. What's more, I have 2 Julia Interpreters on my laptop. One is I installed manually and I added to PATH(By myself)(D:\Environment\Julia). Another is installed automaticlly(When I configure Juno in the app "Atom", another Interpreter installed by Atom.)(C:\Users\Myusername.julia\environments\v1.7)

(I'm not English, so it may be some grammerly wrongs, sorry)

Hey! This package currently supports limited Julia versions, see the README.md file and some other similar issues: https://github.com/JuliaInterop/Cxx.jl/issues/464

You would need to downgrade Julia versions for this to work since you are currently using 1.7.2.

Same error here.

Is this package abandoned???

Or any other options to call C++ code from Julia?
