DRTVWR-489: Fix things up after a messy merge with main because of a gigantic CMake patch. Sadly, my macOS box updated to Xcode14.3 overnight and that caused many warnings/errors with variables being initialized and then used but not in a way that affected anything.. Building on Xcode 14.3 also requires that MACOSX_DEPLOYMENT_TARGET be set to > 10.13. Waiting on a decision about that but checking this in in the meantime.  Builds on macOS with appropriate build variables set for MACOSX_DEPLOYMENT_TARGET = 10.14 but not really expecting this to build in TC because (REDACTED). Windows version probably hopelessly broken - switching to that now.
