Here the diff from Enricos (June) version that I have been using (he has more 
changes in it, but I
think these are the ones relevant for building the fat/universal binary):

    -if (APPLE)
    -# apple build with lower cmake version have an @rpath problem
    -    cmake_minimum_required (VERSION ${CMAKE_VERSION} )
    +if( APPLE )
    +  # apple builds with lower cmake version have an @rpath problem
    +  if( CMAKE_VERSION VERSION_LESS  3.12 )
    +    message( FATAL_ERROR "
    + CMake '3.12' or higher is required, You are running version 
'${CMAKE_VERSION}' " )
    +  endif()
    +  cmake_minimum_required (VERSION ${CMAKE_VERSION} )
     else ()
    -#for other platforms
    -    cmake_minimum_required (VERSION 2.8.12)
    +  #for other platforms
    +  cmake_minimum_required (VERSION 2.8.12)
    +  cmake_policy(VERSION 2.8...3.3)
     endif ()
    -cmake_policy(VERSION 2.8...3.3)

Enrico's entire patch (which includes other things like updating bison) can be 
found here:
