Thanks Michael, but for various reasons, I really don't want all the targets ending up in the same bin directory.  If that's the only way to solve it, then I guess I'll do commands to copy the binaries for a test to a test only directory.

I've tried looking at the target property RUNTIME_OUTPUT_DIRECTORY for the bar and baz targets, but it always somes back as -NOTFOUND, even in the CMakeLists.txts for those targets.  Presumably because I didn't set it in the first place, it just has no value?
