Thanks for trying the release candidate and reporting this issue.

As explained in 0015214:0037064 CMake 3.0 and below were not actually detecting the compiler Xcode uses for a given SDK. It happens to be the same in this case, and so appeared to work before, but it may not be in other cases. CMake 3.1 honors the SDK when building the compiler identification project.

Here is a fix:

 Xcode: Fix compiler path detection for iOS tools on Xcode <= 5.0
 http://cmake.org/gitweb?p=cmake.git;a=commitdiff;h=7f89552a [^]

see commit message for an explanation.
