Cameron Gutman c2d0d784c7 [USB-BRINGUP-TRUNK]
- Create a branch to do a proper merge of USB work from a trunk base instead of from cmake-bringup
- In the future, DO NOT under any circumstances branch another branch. This leads to merge problems!

# add_target_property
# Adds one or more values to the specified property of the specified target.
# Note that there are properties which require (semicolon-separated) lists,
# while others require space-separated strings. The function has a list of
# properties of the former variety and handles the values accordingly
