Currently, Qualcomm's Hexagon SDK can't downloaded automatically via the script build-run-ggmlhexagon-android.sh because of well-known and make-sense IPR policy. I provide a customized&tailored minimal Hexagon SDK to simplify workflow of build ggml-hexagon under the premise of strictly abiding by Qualcomm's IPR policy. At the same time, I strongly recommend that developers should obtain the fully Hexagon SDK with a valid Qualcomm Developer Account because this minimal-hexagon-sdk only used for build ggml-hexagon(in other words, there are only header files and binary programs/libs in this highly-tailored minimal-hexagon-sdk), that's a fully compliant manner and without any IPR concern/risk(Product Kit License Agreement & Export Compliance Assurance).
