[Bf-committers] Cmake OS X Broken?

[Campbell Barton]

After some further investigation (details below), it seems the error
is caused by a mismatch between the OSX version and the SDK version.

Is this something that's normally used/supported on OSX?

----

The error was that `uname -r` outputs, (15.2.0). which causes the SDK
to be set to 10.11, where Jonathan has 10.10 of the SDK. See [0].

Would be good if we could avoid having this list of hard-coded OSX versions.
I think its come up before, this makes OSX unusable for bisecting
since you won't be able to build older versions.

LLVM's compiler-rt for example, uses:

  xcodebuild -version -sdk macosx Path

see source [1].
