build successfully on macOS monterey but can't find old llvm@12 dylib

[Inc0n]

Build was successful using the script copied from #104 (comment), with the only difference that llvm@13 is installed, and all environmental variables are changed accordingly.

However, when running c2ffi, it produced the following error:

dyld[11622]: Library not loaded: /opt/homebrew/opt/llvm@12/lib/libclang-cpp.dylib
  Referenced from: /Users/xception/.local/bin/c2ffi
  Reason: tried: '/opt/homebrew/opt/llvm@12/lib/libclang-cpp.dylib' (no such file), '/usr/local/lib/libclang-cpp.dylib' (no such file), '/usr/lib/libclang-cpp.dylib' (no such file)
zsh: abort      c2ffi

It's trying to find llvm@12, whilst the configured llvm is versioned 13.

The actual build script used

mkdir -p build
cd build
export CPPFLAGS="-I/opt/homebrew/opt/llvm@13/include"
export LDFLAGS="-L/opt/homebrew/opt/llvm@13/lib"
export PATH="/opt/homebrew/opt/llvm@13/bin:$PATH"
LLVM_DIR=/opt/homebrew/opt/llvm@13/ CC="clang" CXX="clang++" cmake --install-prefix ~/.local/bin ..
make
make install

On my macOS Monterey 12.4 with M1 I get the following error with your script
