Depends on:

zstd 1.5.7 Zstandard is a real-time compression algorithm

Depends on when building from source:

cmake 4.4.2 Cross-platform make
ninja 1.13.2 Small build system for use with gyp or CMake
python@3.14 3.14.7 Interpreted, interactive, object-oriented programming language

LLD is now provided in a separate formula:
    brew install lld@19

Using `clang`, `clang++`, etc., requires a CLT installation at `/Library/Developer/CommandLineTools`.
If you don't want to install the CLT, you can write appropriate configuration files pointing to your
SDK at ~/.config/clang.

To use the bundled libunwind please use the following LDFLAGS:
    LDFLAGS="-L$HOMEBREW_PREFIX/opt/llvm@19/lib/unwind -lunwind"

To use the bundled libc++ please use the following LDFLAGS:
    LDFLAGS="-L$HOMEBREW_PREFIX/opt/llvm@19/lib/c++ -L$HOMEBREW_PREFIX/opt/llvm@19/lib/unwind -lunwind"

NOTE: You probably want to use the libunwind and libc++ provided by macOS unless you know what you're doing.
