[CMake] try using the "-03" option to gcc

[Water Lin]

I am trying to use the "-03" option to gcc. But after I use
--------------------
add_definitions(-03)
--------------------

in CMakeLists.txt file and generate the Makefile, I make the project and
gcc provides me a info:
-----------
c++: unrecognized option '-03'
-----------

How can I add "-03" option by CMakeLists.txt?

Thanks

Water Lin
