I didn't test it locally in an x86_64 environment, since I'm now using an aarch64 environment 😅 So it worked with aarch64, but not x86_64:

[0.41s] Configuration failed. This could reflect a misconfiguration of your
[0.41s] toolchains, improper options selected, or another problem. If you
[0.41s] don't see any useful error messages above, the next step is to look
[0.41s] at the configure error log file (config.log) to determine what
[0.41s] configure was trying to do when it died.
[0.42s] [process exited with code 1]

From the README of libvpx:

  1. Prerequisites

    * All x86 targets require the NASM[0] or Yasm[1] assembler be installed[2].

So let's add NASM, and not Yasm (since it's unmaintained), and see if it resolves the issue by just adding the NASM binary to $PATH

LGTM

Tested this time beforehand on x86-64, looks like everything's working now!
