First must go ADD_EXECUTABLE or ADD_LIBRARY and after that

ADD_DEFINITIONS("/EHsc")

Or even something more advanced like this

IF (CMAKE_BUILD_TYPE MATCHES Release)
  IF (CMAKE_USING_VC_FREE_TOOLS)
    SET (CMAKE_CXX_FLAGS_RELEASE_INIT "/MD /O2")
    SET (CMAKE_C_FLAGS_RELEASE_INIT "/MD /O2 /TC")
  ENDIF (CMAKE_USING_VC_FREE_TOOLS)
  SET (DEFINES ${DEFINES} "-DNDEBUG /FD /EHsc /GS /GR /W3 /nologo /c /Wp64")
ENDIF (CMAKE_BUILD_TYPE MATCHES Release)

IF (CMAKE_BUILD_TYPE MATCHES Debug)
  IF (CMAKE_USING_VC_FREE_TOOLS)
    SET (CMAKE_CXX_FLAGS_DEBUG_INIT "/MDd /Zi /Od /RTC1")
    SET (CMAKE_C_FLAGS_DEBUG_INIT "/MDd /Zi /Od /RTC1 /TC")
  ENDIF (CMAKE_USING_VC_FREE_TOOLS)
  SET (DEFINES ${DEFINES} "-D_DEBUG /Gm /EHsc /RTC1 /GR /W3 /nologo /c
/Wp64")
ENDIF (CMAKE_BUILD_TYPE MATCHES Debug)

ADD_DEFINITIONS( -D_MBCS ${DEFINES})

Of course all of this hoes after ADD_EXECUTABLE too
