1、安装依赖包(很重要） 
yum install cmake gcc gcc-c++ gtk+-devel gimp-devel gimp-devel-tools gimp-help-browser zlib-devel libtiff-devel libjpeg-devel libpng-devel gstreamer-devel libavc1394-devel libraw1394-devel libdc1394-devel jasper-devel jasper-utils swig python libtool nasm 

2.安装/更新CMake 

yum install cmake      直接从网上安装cmake

3、安装Opencv 
cmake CMakeLists.txt   

make  
make install

成功 

4.编译

g++ `pkg-config --cflags --libs opencv` code.cpp -o drawing
