 I don't get this; why would you force a dependency on libc++ on non-Mac

 I concur: what's up with this "if" statement? It seems very odd. Let's get
 it fixed & make CMake great again for impacted OSs!

 Maybe with the current MP release we can remove this code entirely since I
 think all of the impacted OSX will use libc++ now anyway ... ?
