Ubuntu18.04 opencv3.3.0
由于做AR需要用到nonfree，所以補充安裝opencv_contrib3.3.0, 但是opencv編譯不成功，請問有人知道怎么解決嗎？
mkdir build
cd build
cmake -DCMAKE_INSTALL_PREFIX=/usr/local/include/opencv3.3.0 -DCMAKE_BUILD_TYPE="Release" -DOPENCV_EXTRA_MODULES_PATH=~/slambook/216/opencv_contrib-3.3.0/modules ..
進行上述指令可以cmake成功，make在18%報錯：
[ 18%] Building CXX object modules/core/CMakeFiles/opencv_perf_core.dir/perf/cuda/perf_gpumat.cpp.o
[ 18%] Building CXX object modules/core/CMakeFiles/opencv_perf_core.dir/perf/opencl/perf_arithm.cpp.o
