Summary0010155: CMAKE_OSX_DEPLOYMENT_TARGET should be optional
DescriptionThe CMAKE_OSX_DEPLOYMENT_TARGET setting should either be optional or there should be a way to disable the -mmacosx-version-min= compiler flag. When building normal iPhone targets (arm architecture) this isn't a problem but if you try to make a iPhomeSimulator target (i386 x86_64) the -mmacosx-version-min clashes with the -miphoneos-version-min= flag:

  make: *** [cmTryCompileExec/fast] Error 2

The only way I have been able to disable this is by optionally unseting CMAKE_OSX_DEPLOYMENT_TARGET in Platform/Darwin.cmake. I don't really understand why the flag is hardcoded into Sources/cmLocalGenerator.cxx...

Fixed in CVS CMake.

cvs commit -m "Fix issue 0010155 - default value of CMAKE_OSX_DEPLOYMENT_TARGET should always be the empty string. When the value of CMAKE_OSX_DEPLOYMENT_TARGET is the empty string, the -mmacosx-version-min flag should not show up on the compiler command line. The logic for selecting default value of CMAKE_OSX_SYSROOT is orthogonal to and independent of the value of the deployment target. The default value for CMAKE_OSX_SYSROOT is the SDK that corresponds to the current version of Mac OSX on which cmake is running."
