Having MACOSX_DEPLOYMENT_TARGET=10.8 env. var breaks cmake invokation. #8

What steps will reproduce the problem?

On command line,
1. export MACOSX_DEPLOYMENT_TARGET=10.8
2. cmake -DCMAKE_TOOLCHAIN_FILE=iOS.cmake -G "Xcode" path_to_project

CMake will report:

Xcode 4.6
Build version 4H127
-- Toolchain using default iOS SDK: 
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer
/SDKs/iPhoneOS6.1.sdk
-- CMAKE_OSX_DEPLOYMENT_TARGET 10.8
CMake Error at /Applications/CMake 
2.8-10.app/Contents/share/cmake-2.8/Modules/Platform/Darwin.cmake:192 (message):
  CMAKE_OSX_DEPLOYMENT_TARGET is '10.8' but CMAKE_OSX_SYSROOT:

   "/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.1.sdk"

  is not set to a MacOSX SDK with a recognized version.  Either set
  CMAKE_OSX_SYSROOT to a valid SDK or set CMAKE_OSX_DEPLOYMENT_TARGET to
  empty.
Call Stack (most recent call first):
  /Applications/CMake 2.8-10.app/Contents/share/cmake-2.8/Modules/CMakeSystemSpecificInformation.cmake:36 (include)
  CMakeLists.txt:42 (project)

-- Configuring incomplete, errors occurred!

As a workaround/remedy, if instead of step 1, one does "export 
MACOSX_DEPLOYMENT_TARGET=", i.e. kills the environment variable, the above 
error doesn't occur.

Should CMake ignore this environment variable when iOS toolchain is used? Can 
this be done from the iOS toolchain itself?

Thanks!

Good find. Should be easy enough to fix by unsetting that value in the 
toolchain. Will test and fix.

Looks like this just showed up in cmake 2.8.10. Fixed by forcefully unsetting 
CMAKE_OSX_DEPLOYMENT_TARGET as a cache value in the toolchain.

Thanks for the quick fix! Tested the fix without my manual workaround, and it 
works perfectly!
