Still I'm surprised that in your case, add_definitions(-D_UNICODE) does 
not automatically remove the definition of _MBCS. Do you even have _MBCS 
for a simple CMakeLists.txt as follows?

   ############################################################
   # CMakeLists.txt
   project( MyCMakeMfcUnicodeApp )
   cmake_minimum_required(VERSION 2.8)
   set(CMAKE_MFC_FLAG 2)
   add_definitions(-D_UNICODE)
   add_executable(${PROJECT_NAME} MySourceFile.cpp)
   ############################################################

Having the following "MySourceFile.cpp":

   ////////////////////////////////////////////////////////////
   // MySourceFile.cpp
   #ifdef _MBCS
   #  error "_MBCS should not be defined!"
   #endif
   ////////////////////////////////////////////////////////////


Kind regards,
