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 && cmake -DCMAKE_INSTALL_PREFIX=/usr \ -DWITH_XINE=ON \ -DBUILD_TESTS=OFF \ -Wno-dev .. make
The package does not come with an operable test suite.
Now, as the root
user:
make install
-DWITH_XINE=ON
: This option
instructs the make procedure to use xine-lib-1.2.6.
-DWITH_IPP=ON
: This option
instructs the make procedure to use the downloaded IPP package.
