下载2.0版本，解压

编译过程：

cd OpenCV-2.0.0/
mkdir release
cd release
cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/opt/opencv -D BUILD_PYTHON_SUPPORT=ON ..


配置：

在.bashrc中：

export LD_LIBRARY_PATH=/opt/opencv/lib/:$LD_LIBRARY_PATH

不然会出现类似：error while loading shared libraries: libcxcore.so.2.0: cannot open shared object file: No such file or directory

这样的错误。

编译命令：

gcc -o output source.c -I/opt/opencv/include/opencv -I/opt/opencv/include -L/opt/opencv/lib/ -lcxcore -lcv -lcvaux -lhighgui -lml

这样在包含头文件的时候就需要#include <opencv/header.h>

至此就可以正常编译运行了。
