使用cmake生成第一个opencv工程

VS2010编译好OpenCV3.1.0后，想自己新建一个工程，使用了cmake生成。

先新建一个文件夹，里面存放两个文件和一个图像文件，再另外新建一个build文件夹。

OpenCVHello_cmake\CMakeLists.txt
OpenCVHello_cmake\OpenCVHello.cpp
OpenCVHello_cmake\ubuntu.png
OpenCVHello_cmake\build

文件1、CMakeLists.txt

#CMakeLists.txt
cmake_minimum_required( VERSION 2.8 )
project( OpenCVHello )

# 添加c++ 11标准支持
set( CMAKE_CXX_FLAGS "-std=c++11" )

# 寻找OpenCV库
set(OpenCV_DIR "D:\\OpenCV\\opencv-3.1.0\\opencv\\build\\install")
find_package( OpenCV REQUIRED )
# 添加头文件
include_directories( ${OpenCV_INCLUDE_DIRS} )
#include_directories( "D:\\OpenCV\\opencv-3.1.0\\opencv\\build\\install\\include" )



add_executable( OpenCVHello OpenCVHello.cpp )
# 链接OpenCV库
target_link_libraries( OpenCVHello ${OpenCV_LIBS}

文件2：OpenCVHello.cpp

#include <opencv2/core/core.hpp>
#include <opencv2/imgcodecs.hpp>
#include <opencv2/highgui/highgui.hpp>
#include <iostream>
#include <string>
using namespace cv;
using namespace std;
int main( int argc, char** argv )
{
    string imageName("E:\\FENG\\workspace_vc10\\OpenCVHello_cmake\\ubuntu.png"); // by default
    if( argc > 1)
    {
        imageName = argv[1];
    }
    Mat image;
    image = imread(imageName.c_str(), IMREAD_COLOR); // Read the file
    if( image.empty() )                      // Check for invalid input
    {
        cout <<  "Could not open or find the image" << std::endl ;
        return -1;
    }
    namedWindow( "Display window", WINDOW_AUTOSIZE ); // Create a window for display.
    imshow( "Display window", image );                // Show our image inside it.
    waitKey(0); // Wait for a keystroke in the window

	system("pause");
    return 0;
}

图像文件自己任选。

使用cmake-gui，生成vs2010工程文件。

在vs2010界面，按F5，出现了错误……见下文。

如果用VS2010编译工程时出现以下问题：

网上资源整理如下：

解决方法一（已验证可用）：VS2010：工具--》选项--》》调试--》符号，选择Microsoft，然后确认

接着随便编译一个程序，过程会灰常的慢。看到此目录下符号缓存了吗？C:\Users\XXX\AppData\Local\Temp\SymbolCache 找到这个目录拷贝出来，找个地方存放。接下来就是去掉Microsoft符号服务器，要是不去，每次都要从Microsoft下载很麻烦，已经缓存了，我们就可以利用好这些缓存。

解决方法二（未测试）：

1. Ctrl + F5运行就可以了(最好的解决方案)

2. 在cmd命令行下执行程序。
3. 把"Microsoft Symbol Servers"勾上(Tools -> Options -> Debugging -> Symbols).
4. http://blog.163.com/chenpeijie0_0/blog/static/1830945712011780275118
原因：程序输出的地方是系统而不是vs2012

5.Debug->Options and Settings->The left to check: Enable Source server support->Symbols->the left to check: Microsoft Symbol Servers->Runing(F5)->OK

注：解决方案还有就是在每个main函数结束的时候即return 0之前加上 system("pause")；

程序运行结果：
