Compile OpenCV with neon support

I’ve heard about Neon support in OpenCV.
http://processors.wiki.ti.com/index.php/Building_OpenCV_for_ARM_Cortex-A8

I want to compile OpenCV 2.4 for my BB (running Ubuntu 11.10), but cannot find the flag to enable Neon.
Is it enable by default? I don’t think so but what is the flag?

Maybe I’ve found the answer.

Edited file cmake/OpenCVCompilerOptions.cmake:
changed
set(OPENCV_EXTRA_C_FLAGS_RELEASE “”)
to
set(OPENCV_EXTRA_C_FLAGS_RELEASE “-O2 -mfpu=neon -mfloat-abi=softfp”)
