Ubuntu16.04環境下通過Cmake管理Opencv專案

1、新建qt cmake工程

New Project -> Non-Qt Project -> Plain C++ Application

2、CMakeLists.txt檔案內容修改為如下：

//gh
project(untitled2)

# 新增c++ 11標準支援
set( CMAKE_CXX_FLAGS "-std=c++11" )

# 尋找OpenCV庫
find_package( OpenCV REQUIRED )
# 新增標頭檔案
include_directories
 
( ${OpenCV_INCLUDE_DIRS} )

# add sourcce files: *.cpp
aux_source_directory(. SRC_LIST)

add_executable(${PROJECT_NAME} ${SRC_LIST})

# 連結OpenCV庫
target_link_libraries( ${PROJECT_NAME} ${OpenCV_LIBS} )

3 、main.cpp內容為：

#include <iostream>
#include<opencv2/opencv.hpp>
using namespace std;
 

using namespace cv;
int main()
{
   Mat image = imread("ubuntu.png",IMREAD_COLOR);
   if(image.data == nullptr)
       cout<<"files doesn't exist"<<endl;
   else
       cout<<"success!"<<endl;
   cout << "Hello World!" << endl;
   imshow("test",image);
   waitKey (
 
 0 );                  // 暫停程式,等待一個按鍵輸入
   return 0;
}

4、工程專案右鍵依次執行：

build -> run
