OS X support adjustments

[tuscland]

Hello,

Here are a couple of adjustments for build the SDK under OS X with OpenCV-2.4.6.1.
Note that for OpenCV I had to use the following options:

cmake -G "Unix Makefiles" \
    -DCMAKE_INSTALL_PREFIX=/usr/local/opencv/ \
    -DCMAKE_OSX_ARCHITECTURES=x86_64 \
    -DBUILD_PERF_TESTS=OFF \
      -DBUILD_TESTS=OFF \
      -DBUILD_WITH_DEBUG_INFO=OFF \
      -DBUILD_opencv_nonfree=OFF \
      -DBUILD_opencv_ocl=OFF \
    -DCMAKE_BUILD_TYPE=Release \
      -DENABLE_AVX=ON \
      -DENABLE_FAST_MATH=ON \
      -DENABLE_SSE=ON \
      -DENABLE_SSE2=ON \
      -DENABLE_SSE3=ON \
      -DENABLE_SSE41=ON \
      -DENABLE_SSE42=ON \
      -DENABLE_SSSE3=ON \
      ..

Best,
Cam

Oh, hey, I asked somewhere else about why you had not made a pull request for your fixes. I now see that you in fact did make one .. sorry for the confusion.
