[osg-users] [build] Xocde 7.1 with osgDB compiler error

[Robert Osfield]

Hi Radu,

What errors do you see with your build when you don't include the
IF(MACOS_VERSION_LIST_LENGTH EQUAL "3") block to avoid querying the
MACOS_VERSION_PATCH?

With this block I'd be inclined to use GREATER 2, rather than EQUAL 3 just
in case the MACOS implementation adds a forth element to the list.

Robert.
