Update Pull #443, allow multiple config files

jphickey · jphickey · commit 20f8b188f113 · 2020-05-04T16:29:26.000-04:00
The "include()" cmake function only read the first file when passed a list.
Adding a foreach loop supports allowing a list of files which is useful
for adding and override/addendum file to a base config.
