Hmm. Haven't seen that one in a while. It used to be a problem in cmake-2.x because they'd defined some dumb 
defaults, but they'd fixed that by 3.2.1. 

Make sure that your prefix and build directory are empty and that your environment has no CMAKE_ variables 
set. Also check ~/.jhbuildrc-custom for CMAKE variables. If all else fails you can export 
CMAKE_OSX_SYSROOT=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk
and
CMAKE_OSX_DEPLOYMENT_TARGET="10.11"

and select 6 "wipe directory and start over". The last is important because cmake caches parameters and 
ignores new settings so you need a pristine build directory for each try.
