Failed to run custom build commads for llvm-sys v150.0.5

[ASoldo]

Describe the Bug
I have started to explore how to make a programming language using Rust. I have created interpreter and parser and it works great. I've tried to use inkwell to compile my script with llvm. Compiler seems to be with no errors but when I try to cargo build or cargo run I encounter a problem. When I try to compile my project within Rust I get this error message:

cargo build                                                                                                                                                                                              ✔  system      00:42:39   

I know it's much to ask but maybe I've made some rookie mistake and someone can spot that.
Thank you!

This issue was solved by healdove in gitter channel.
Since I use Arch Linux LLVM was not complete and that's why I had this error.

in order to solve it, healdove provided me with this link ---> https://github.com/llvm/llvm-project/releases/tag/llvmorg-15.0.0
i had to extract this file and put it somewhere safe like in my ~ location in llvm folder.
then in my .zshrc I have exported usual variables for

export LLVM_SYS_150_PREFIX=~/llvm/clang+llvm-15.0.0-x86_64-linux-gnu-rhel-8.4

export LLVM_CONFIG_PATH=/usr/bin/llvm-config

and it worked.
thank you healdove for quick help and explanations.
