// Use the following helpers to define build settings whose value depends on the target
// macOS version in a succinct and future-proof way.
//
// Example 1: To give the SMOOTHNESS build setting the value 3 in macOS 10.12 and later and the
// value 2 in earlier versions, write:
//
//     SMOOTHNESS = $(SMOOTHNESS$(WK_MACOS_1012));
//     SMOOTHNESS_MACOS_BEFORE_1012 = 2;
//     SMOOTHNESS_MACOS_SINCE_1012 = 3;
//
// Example 2: To define ENABLE_COLOR to ENABLE_COLOR in all platforms except macOS 10.12 and
// earlier write:
//
//     ENABLE_COLOR = ENABLE_COLOR;
//     ENABLE_COLOR[sdk=macosx*] = $(ENABLE_COLOR$(WK_MACOS_1013));
//     ENABLE_COLOR_MACOS_SINCE_1013 = $(ENABLE_COLOR);
//
// Example 3: To give EXTRA_PATH one value before macOS 10.12, another value in macOS 10.12 and
// macOS 10.13, and a third value in macOS 10.14 and later, write:
//
//     EXTRA_PATH = $(EXTRA_PATH$(WK_MACOS_1012_1014));
//     EXTRA_PATH_MACOS_BEFORE_1012 = "/Library/Application Support/WebKit";
//     EXTRA_PATH_MACOS_BEFORE_1014 = /System/Library/CoreServices;
//     EXTRA_PATH_MACOS_SINCE_1014 = /System/Library/PrivateFrameworks;

// macOS
