Darwin: Remove deployment target version check
Starting with Xcode 8 the SDK folder also contains an unversioned entry:
MacOSX.sdk
MacOSX10.12.sdk -> MacOSX.sdk
If this unversioned path is used CMake cannot detect the SDK version.
Furthermore, querying the SDK version via
xcodebuild -sdk <sysroot> -version Path
gives bogus results for the Command Line Tools installed into /
.
The OS X deployment target version and SDK version are not as tied as they once were, so this check is now more trouble than it is worth. Simply remove it.
