User Notes:

Installation of opencv

If the optional Integrated Performance Primitives (IPP) package has been downloaded, put it in place so the cmake script does not try to download it again:

ipp_file=../ippicv_linux_20151201.tgz             &&
ipp_hash=$(md5sum $ipp_file | cut -d" " -f1)      &&
ipp_dir=3rdparty/ippicv/downloads/linux-$ipp_hash &&

mkdir -p $ipp_dir &&
cp $ipp_file $ipp_dir

Install opencv by running the following commands:

mkdir build &&
cd    build &&

      -DWITH_XINE=ON              \
      -DBUILD_TESTS=OFF           \
      -Wno-dev  ..

The package does not come with an operable test suite.

Now, as the root user:

make install
