This is how it worked for me:

install https://brew.sh/

Install required packages brew install llvm libomp

in command line set variables that will be used for compilation (can be done by editing .zprofile):

export PATH="/opt/homebrew/opt/llvm/bin:$PATH"
export LDFLAGS="-L/opt/homebrew/opt/llvm/lib"
export CPPFLAGS="-I/opt/homebrew/opt/llvm/include"

compile program clang++ -fopenmp --std=c++11 -stdlib=libc++ lab04.cpp -o lab04 && ./lab04

worked perfectly for me.
clang++ -fopenmp proj.cpp -o proj

Does anyone know how to install Libomp without homebrew?
I do not want to use homebrew on my Mac for some limitations.
