I have steal the macro about SIMD from 
https://code.ros.org/svn/ros/stacks/ros/tags/cturtle/core/rosbuild/public.cmake
and paste it in CMakeLists.txt. 
But I get many errors like this:
/home/tangm/ros_sandbox/versioned_latest/stacks/collision_environment/collision_space/include/kDOP16-sse.h:126:
error: ‘__declspec’ was not declared in this scope 
Many variables haven't been defined.
I need your help. Thanks.
