[cmake-developers] [PATCH] Retrieve Xcode CompilerId via static libraries

[Gregor Jasny]

The current approach to determine the CompilerId via
an XCTest bundle on iOS requires a valid code sign identity.

This is a regression compared to CMake 3.0. This patch changes
the detection to be performed on a static library and also
unifies detection across iOS and OSX.

This has been tested on OSX 10.10 with Xcode 6.1.1.
