Hi,
Sorry completely missed your question somehow.
This is a rough procedure from my notes to build it (I hope it'll help)
git clone https://git.openwrt.org/openwrt/openwrt.git
cd openwrt
optional to see what's available (i used OpenWrt 19.07 branch)
git checkout openwrt-19.07
Fetch and list tags
git fetch --tags
git tag -l
Use OpenWrt 19.07.7 release
git checkout v19.07.7
./scripts/feeds update -a
./scripts/feeds install -a
wget https://downloads.openwrt.org/releases/19.07.7/targets/armvirt/64/config.buildinfo -O .config
make defconfig
make menuconfig
You also you need to make sure you have :
CONFIG_PACKAGE_kmod-usb-net-pl=y
or you won't be able to use the keyboard from ESXI Console
Before you "make" see below for needed config-default required options
make
Check the below items are present in config-default (some items are already present so do a compare, although I suppose repeated options won't do any harm anyway):

The above is same as what was posted on Arm fling installation - #4 by statto99 but a config option was missing and generating the following error:
error: plain image kernel not support - rebuild with CONFIG_(U)EFI_STUB
In short you'll also need to add:
CONFIG_(U)EFI_STUB=y
After my compare I was missing and had to add the following to the bottom of the file /openwrt/target/linux/armvirt/64/config-default, but please do your compare if you are using a different version

Follow steps on other posts to package it up, however I would just edit the previous .vmdk provided in this post rather than recreate it from scratch.
If you run into issue I'll try my best to help.
Some very useful resources that should help:
