[Bf-committers] mac OSX 10.10.5 and Xcode 7 cmake fix

[Levon]

Overnight my computer auto updated to OSX 10.10.5 (from 10.10.4) and to
Xcode 7.0. even though auto updates were turned off.

OSX 10.10.5 and xcode 7.0 introduce a new SDK version of 10.11 which
src/blender/CMakeLists.txt is not aware of.


Fortunately uname -r reports the system as 14.5 now.

patch to fix it.
