P4 to Git Change 1518310 by msearles@zuni-1666 on 2018/02/22 13:02:34

SWDEV-102733 - Update some CMakeLists.txt files:
	      - when setting CMAKE_CXX_FLAGS, append to it rather than overwriting it.
	      - some linker flags, -Wl,--unresolved-symbols=report-all being one of them, requires -shared-libasan if using -fsanitize=address.
