# script fails on any missing bundle.resources path, and neither entry point
# builds the engine worker or the ggml backends.

#
# JAN_ENGINE_VARIANT picks the GPU backends compiled into the worker. Vulkan is
# in every variant, not just the default: it is the fallback when the CUDA or
# ROCm runtime turns out to be missing or too old on the user's machine, and
# ggml chooses between the registered backends at runtime.
#
# The CPU backend is always multi-versioned (GGML_CPU_ALL_VARIANTS), so every
# variant ships the full set of x86-64/ARM microarchitecture modules and ggml
# scores them at load time. That is what "common CPUs" means here.
#
# The variant is a `-` separated list of backends, so a shipping build names
# every backend it carries and one worker covers the machine it lands on:
#
#   vulkan  (default)  vulkan
#   cuda13             cuda + vulkan   (needs CUDA 13 toolkit on PATH)
#   cuda12             cuda + vulkan   (needs CUDA 12 toolkit on PATH)
#   rocm               hip  + vulkan   (needs ROCm/HIP)
#   cuda13-hip-vulkan  all three       (needs the CUDA and the HIP toolkit)
#
# cuda12 and cuda13 cannot be combined: the CUDA major is whichever nvcc is on
# PATH, one toolkit per configure, and both emit libggml-cuda.so.
#
# CUDA 12 vs 13 is not a cmake flag -- it is whichever nvcc is found ($CUDACXX,
# else PATH). On x86_64, build.rs passes ggml-cuda's default arch list for that
# version with Turing as native code (#9185); it only adds the 50/61/70 virtual
# archs below CUDA 13. They are still
# separate variants because the resulting binaries cover different GPUs, so
# check-engine-toolchain asserts the toolkit matches the variant name rather
# than letting a cuda13 build ship labelled cuda12.
