Your compiler doesn't support "blocks":

<https://en.wikipedia.org/wiki/Blocks_(C_language_extension)>

and the latest OS X SDKs require such support.  You could try building CMake against an older SDK, or just use clang, the default compiler on OS X.

I think Apple added blocks support to their fork of gcc (long ago), but I don't think it ever went into mainline gcc.

Cheers,
