I do not have any special configure. Here is my `cmake` command:
```
cmake -G "Unix Makefiles" -DCMAKE_BUILD_TYPE=Release $HOME/wrk/llvm/tmp/llvm-project/llvm \
  -DCMAKE_INSTALL_PREFIX=$HOME/wrk/llvm/tmp/llvm-install -DLLVM_TARGETS_TO_BUILD="AArch64" \
  -DCMAKE_OSX_ARCHITECTURES="arm64" -DLLVM_ENABLE_PROJECTS="clang;flang;mlir" \
  -DLLVM_ENABLE_RUNTIMES="openmp;compiler-rt" -DDEFAULT_SYSROOT="$(xcrun --show-sdk-path)" \
  -DCMAKE_CXX_COMPILER=$HOME/wrk/llvm/17.0.4/bin/clang++ \
  -DCMAKE_C_COMPILER=$HOME/wrk/llvm/17.0.4/bin/clang \
  -DBUILTINS_CMAKE_ARGS=-DCOMPILER_RT_ENABLE_IOS=OFF \
  -DLLVM_LIT_ARGS="--threads=8 -v --show-unsupported"
```
