sweet ! I just found out how to return the value of a cmake script
back to ADD_TEST:

MACRO(TEST command expected)
  IF("x${result}" STREQUAL "x${expected}")
    #MESSAGE("TEST \"${command}\" success: \"${result}\" expected:
\"${expected}\"")
  ELSE("x${result}" STREQUAL "x${expected}")
    MESSAGE(SEND_ERROR "${CMAKE_CURRENT_LIST_LINE}: TEST
\"${command}\" failed: \"${result}\" expected: \"${expected}\"")
  ENDIF("x${result}" STREQUAL "x${expected}")
ENDMACRO(TEST command expected)

  MESSAGE(SEND_ERROR was the key.

thanks bill !
