Building oidn on Ubuntu 18.04 ARM64

Hi,
Using 1.4.1 code base as a reference, I am able to build oidn on Ubuntu 18.04 Intel x86_64
However, attempting to build the same code base on Ubuntu 18.04 ARM64 produces these errors, I am wondering if others have encountered similar errors and how it can be resolved ?
