[CMake] set_target_properties not setting COMPILE_DEFINITIONS?

Ahhh it all makes sense now. I'm very sorry, I didn't realize the Tech
files had been broken out into a separate static library. I was just
assuming I was doing something wrong with set_target_properties etc
since I had not used it before, but the problem was so obvious!

Thank you all very much for your help - at least I learned some good
debugging commands along the way.
