--tflite-delegate
setup dependencies for the Arm NN TF Lite Delegate
--tflite-parser
setup dependencies for the Arm NN TF Lite Parser
--onnx-parser
setup dependencies for the Arm NN ONNX parser
--all
setup dependencies for all Arm NN components listed above
--target-arch=[aarch64|x86_64]
specify a target architecture (mandatory)
--num-threads=<INTEGER>
specify number of threads/cores to build dependencies with (optional: defaults to number of online CPU cores on host)
-h, --help
print brief usage information and exit

enable shell tracing in this script
At least one dependency flag (e.g. --tflite-delegate) must be provided or else provide --all to setup all dependencies.
Directories called "source" and "build" will be generated in the current directory (ROOT_DIR) from which this script is called.
It's recommended to call this script in a directory outside of this Arm NN source repo, to avoid nested repositories.
Examples:
Setup for aarch64 with all Arm NN dependencies:
<PATH_TO>/setup-armnn.sh --target-arch=aarch64 --all
Setup for aarch64 with TF Lite Delegate and TF Lite Parser dependencies only:
<PATH_TO>/setup-armnn.sh --target-arch=aarch64 --tflite-delegate --tflite-parser
