Description of Change(s)

The previous line produces a warning on GCC13.

warning: suggest parentheses around assignment used as truth value [-Wparentheses]
  408 |         if (destSpec = (_composedPropertyLayer->GetObjectAtPath(
      |             ~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
  409 |                 primPath.AppendProperty(propName)))) {
      |                 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

In #3334, @dgovil suggests this occurs on clang 16 too. Putting parentheses around the expression confirms that the assignment as truth value is intentional.
