There must be something else as well. See output below:

 [jim at nucboxg3 ~]$ echo $MYTHTVDIR
/usr/local

Even though it's looking the a different place, the files are there:

cd mythtv-qt5-output/share/mythtv/html/apps/backend/
[jim at nucboxg3 backend]$ ls
3rdpartylicenses.txt  color.png  favicon.ico  hue.png  index.html  main.js
 polyfills.js  runtime.js  styles.css
[jim at nucboxg3 backend]$
