add_compile_options add to the directory COMPILE_OPTIONS property; it seems that setting target specific COMPILE_OPTIONS will only use the current directory COMPILE_OPTIONS at the time the target_compile_options is encountered, but ignore later ones. Long story short: move the compile options further up, and the /W3 and /MP ones to the toplevel so they also apply to the Editor and Samples.
