Some things just can not be done cross platform. For example reading/ writing the windows registry, creating an OSX application bundle, and sym-links. Also, some computers don't even have shared libraries. Should we disable those features from CMake? That said, the symlink command is the only -E that does not work cross platform. The -E create_symlink does return failure from main when called on windows. So, if you used it in a custom command which is the idea for -E stuff, it would fail in a noticeable way (the build would fail). If you call it from execute_process, you should be checking the return value as well.
I guess I am the victim of the assumption that all cmake -E commands are supposed to work cross-platform since all of them do so (which I was glad to hear) other than create_symlink. Right now, here is what cmake -E help says about that command. create_symlink old new - create a symbolic link new -> old If you simply added (UNIX ONLY) to that documentation string, then users like me wouldn't make unwarranted assumptions.
