# engine (llama.cpp). build-essential and libcurl-dev are also needed on Linux.
# cmake/git are only needed to *build* llama.cpp from source. Studio downloads a
# prebuilt by default, and setup.sh self-skips the source build when they're
# absent -- so macOS doesn't block on cmake (requiring it would force a manual
# Homebrew install). Linux keeps requiring them; its package manager has them.
