building ipp-crypto fails

I'm attempting to test hardware accelerated openssl libraries, and am following the steps outlined in:
https://github.com/intel/ipp-crypto/blob/develop/BUILD.md
This is being built under vmware workstation 15 with an x64 Ubuntu 20 guest on a windows 10 pro host box running amd ryzen 3950 processor. It appears from docs i should be able to build (not run) on a non-intel system, or am i mistaken?

cmake setup works, but build fails before completion:

```

```

Update: set up a build environment on a dell r740 running ubuntu 20 x64. same issue.
