[Bf-committers] Cmake OS X Broken?

[Levon]

This came up last Sept.

This is the original thread.

http://lists.blender.org/pipermail/bf-committers/2015-September/045905.html

This patch posted above wasn't ever committed, it was only ever fixed for
version 15, not 14.5

You can also simlink the sdk directory to version 10 and it will work fine
(for now)

Osx also deletes the old SDK when you update, so compiling old versions of
the SDK requires downloading again.
In my case xcode updated automatically and removed the old SDK.

However, compiling with osx10.6 compatability means it will work fine on
older systems.
