Summary:                    CMake fails with XCode 4.6 and Qt 4 with
CMAKE_OSX_DEPLOYMENT_TARGET
Description: 
CMake fails to set up CMAKE_OSX_SYSROOT when using XCode 4.6 with command line
tools installed. I have only 10.7 and 10.8 SDKs installed.

A minimal CMakeLists.txt to reproduce the issue is:

PROJECT(test)
SET(CMAKE_OSX_DEPLOYMENT_TARGET 10.5)
FIND_PACKAGE(Qt4 COMPONENTS QtCore)


CMake outputs the following errors:

CMake Warning at

  Instead using SDK:

 "/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.7.sdk"

  matching the host OS X version.

CMake 2.8.9 works fine. I haven't tested with CMake 2.8.10 or 2.8.11.
