Sysdeps are libraries (zlib, zstd, elfutils, libdrm, numactl, etc.) that we build from source with special packaging treatment — SONAME rewriting, symbol versioning, and installation into lib/rocm_sysdeps/ — so that ROCm can ship private copies without conflicting with system-installed versions.

This is distinct from the other third-party libraries under third-party/ (fmt, spdlog, flatbuffers, etc.), which are build dependencies not given special treatment for portable distribution. See Dependencies for the full explanation of the two categories.
