Here's what I use for the BeagleBoard X15. Should be adaptable to other
boards by changing -march and -mtune.
cmake -DCMAKE_CXX_FLAGS:STRING="-march=armv7-a -mfloat-abi=hard
-mfpu=neon -mtune=cortex-a15" -DCMAKE_C_FLAGS:STRING="-march=armv7-a
-mfloat-abi=hard -mfpu=neon -mtune=cortex-a15" ../

You need to specify the right cmake toolchain in order to enable the
use of NEON kernels.
Cheers,
