# This script is intended to run inside the go generate
# working directory must be llm/generate/

# First we build our default built-in library which will be linked into the CGO
# binary as a normal dependency. This default build is CPU based.
#
# Then we build a CUDA dynamic library (although statically linked with the CUDA
# library dependencies for maximum portability)
#
# Then if we detect ROCm, we build a dynamically loaded ROCm lib.  ROCm is particularly
# important to be a dynamic lib even if it's the only GPU library detected because
# we can't redistribute the objectfiles but must rely on dynamic libraries at
# runtime, which could lead the server not to start if not present.
