    {*}${description} \
    Features: \
    - Zlib compatible API with support for dual-linking \
    - Modernized native API based on zlib API for ease of porting \
    - Modern C11 syntax and a clean code layout \
    - Deflate medium and quick algorithms based on Intel\’s zlib fork \
    - Support for CPU intrinsics when available \
    - Unaligned memory read/writes and large bit buffer improvements \
    - Includes improvements from Cloudflare and Intel forks \
    - Configure, CMake, and NMake build system support \
    - Comprehensive set of CMake unit tests \
    - Code sanitizers, fuzzing, and coverage \
    - GitHub Actions continuous integration on Windows, macOS, and Linux \
    - Emulated CI for ARM, AARCH64, PPC, PPC64, RISCV, SPARC64, S390x using \
      qemu
