Hi,

I'm trying to build LibFuzzer in my macOS 14.4.1 arm64 architecture. I used the cmake command:

cmake -S llvm -B build -G Ninja \ -DLLVM_ENABLE_PROJECTS="clang;lldb" \ -DLLVM_ENABLE_RUNTIMES="libcxx" \ -DCMAKE_BUILD_TYPE=Debug \ -DLLVM_TARGETS_TO_BUILD="AArch64" \ -DLLVM_ENABLE_ASSERTIONS=ON \ -DLLVM_USE_SANITIZER=Address \ -DLLVM_USE_SANITIZE_COVERAGE=On \ -DLLDB_USE_SYSTEM_DEBUGSERVER=ON \ -DCMAKE_C_COMPILER=/opt/homebrew/opt/llvm/bin/clang \ -DCMAKE_CXX_COMPILER=/opt/homebrew/opt/llvm/bin/clang++ \ -DCMAKE_OSX_ARCHITECTURES='arm64' \ -DCMAKE_CXX_FLAGS="-isysroot /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk"

But then when I build it, I got the error:

llvm-project/llvm/tools/vfabi-demangle-fuzzer/vfabi-demangler-fuzzer.cpp:20:16: error: variable has incomplete type ‘SMDiagnostic’
20 | SMDiagnostic Err;
