Also,
    Are you using the Eclipse generator or just the Makefiles  
generator? Also what version of CMake.

You may be able to wrap the -fmessage-length=0 in some cmake code  
based on the generator being used.

IF( CMAKE_GENERATOR STREQUAL "Eclipse CDT4")
   SET(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} -fmessage-length=0")
ENDIF( CMAKE_GENERATOR STREQUAL "Eclipse CDT4")
IF( CMAKE_GENERATOR STREQUAL "Eclipse CDT4")
   SET(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -fmessage-length=0")
ENDIF( CMAKE_GENERATOR STREQUAL "Eclipse CDT4")
