Yeah, that seems to be the problem.
Dennis, can you edit your Qt4Macros.cmake in the cmake installation and 
fix the following section to

   FOREACH(_current ${_inc_DIRS})
     IF("${_current}" MATCHES "\.framework/?$")
       STRING(REGEX REPLACE "/[^/]+\.framework" "" framework_path 
"${_current}")
       SET(${_moc_flags} ${${_moc_flags}} "-F${framework_path}")
     ELSE("${_current}" MATCHES "\.framework/?$")
       SET(${_moc_flags} ${${_moc_flags}} "-I${_current}")
     ENDIF("${_current}" MATCHES "\.framework/?$")
   ENDFOREACH(_current ${_inc_DIRS})

Let me know if that works for you.
