```
Follow https://github.com/openwrt/openwrt/blob/master/README.md directions to prep environment and build openwrt

After many minutes/hours of building, observe `make` fails due to an issue with path:

This was the command:
find /home/ubuntu/openwrt/build_dir/target-arm_cortex-a15+neon-vfpv4_musl_eabi/root-ipq806x/ -mindepth 1 -execdir touch -hcd "@1587126718" "{}" +

The was the error:
find: The relative path 'Files/WindowsApps/CanonicalGroupLimited.UbuntuonWindows_1804.2020.5.0_x64__79rhkp1fndgsc' is included in the PATH environment variable, which is insecure in combination with the -execdir action of find. Please remove that entry from $PATH

Workarounds:
Remove all paths from $PATH that have spaces
