Let me start by saying I've never used cmake ...

Can you try adding the red text in src/Sigil/CMakeLists.txt:

# For Mac, add frameworks and make a DMG
if( APPLE )
    set (CMAKE_OSX_ARCHITECTURES "i386;x86_64" )
    if(CMAKE_GENERATOR STREQUAL Xcode)
        set( WORK_DIR "${CMAKE_RUNTIME_OUTPUT_DIRECTORY}/Release" )
    else()
        set( WORK_DIR "${CMAKE_RUNTIME_OUTPUT_DIRECTORY}" )
    endif()

or (trying to do the same thing from the command line) using

-DCMAKE_OSX_ARCHITECTURES="i386;x86_64"

as an argument to cmake?

This is all thanks to Mr Google, and completely untested .

Cheers,
Simon.
