Description
When building LLVM 20.1.6 on MacOS 15.5,
cmake --debug-output -S llvm -B build -G Ninja -DCMAKE_BUILD_TYPE=Debug -DCMAKE_OSX_ARCHITECTURES='arm64' -DCMAKE_C_COMPILER=/usr/bin/clang -DCMAKE_CXX_COMPILER=/usr/bin/clang++
and
ninja -C build
I ran into the following error while building:
[203/3857] Building AArch64TargetParserDef.inc...

I have libzstd.1.dylib in usr/local/lib. To resolve the error I had to do -DLLVM_USE_STATIC_ZSTD=TRUE.
I was building LLVM recently without having to do this, could something have changed to cause this?
