+# NOTE: SYSROOT ought to be programmatically determined using XCODE_PATH, however since upgrading my build environment to El Capitan xcode-select returns a non-useful path, hence I am forced to set the SYSROOT explicitly for my build environment, which is now a hybrid of XCode 3.2.6 'running' on OS X 10.11. I am not going to risk upgrading XCode for fear of losing the ability to target down-level OS X versions.
