本文提供OpenCV2.4.13版本的详细安装步骤，包括依赖库安装、配置编译参数及解决Qt5Core配置文件缺失等问题。

`openCV2.4.13` 安装

下载并解压
```
unzip opencv-2.4.13.zip
```
进入openCV目录,建立release文件夹
```
cd opencv-2.4.13
mkdir release
```

安装依赖库

sudo apt-get install build-essential cmake libgtk2.0-dev pkg-config python-dev python-numpy libavcodec-dev libavformat-dev libswscale-dev 

sudo apt-get install -x264 v4l-utils ffmpeg

进入release目录,cmake编译,把lib安装到 /usr/local/目录下

cmake -D CMAKE_BUILD_TYPE=RELEASE  \
-D CMAKE_INSTALL_PREFIX=/usr/local \
-D WITH_TBB=ON \
-D BUILD_NEW_PYTHON_SUPPORT=ON \
-D WITH_V4L=ON \
-D INSTALL_C_EXAMPLES=ON \
-D INSTALL_PYTHON_EXAMPLES=ON \
-D BUILD_EXAMPLES=ON \
-D WITH_QT=ON \
-D WITH_OPENGL=ON ..

安装
```
sudo make install
```

如果不想安装到/usr/local目录下的话,咋整?

坑
