[C++]vscode中 opencv导入和配置

Reference with full tutorial： https://blog.csdn.net/you_zai/article/details/119848662 

 

QuickStart ：

vscode : https://code.visualstudio.com/download

minGW : https://sourceforge.net/projects/mingw-w64/files/

opencv built version for windows : https://pan.baidu.com/s/1Npb0NQbQnjUmWq_VSGJz8g    code : TXSB

 

Step：

1. You don't have to build opencv source code. just follow the link above, and you will get a bulit one.

2. ensure you add all the environment path , openccv ,minggw.

3. install C/C++ extension in VScode , just following another blog in my homepage.

4. There are 2 methods to compile files

　　a . the following is json file sample

　　b. use cmake

tasks.json

{
    "tasks": [
        {
            "type": "cppbuild",
            "label": "C/C++: g++.exe build active file",
            "command": "C:\\Dev\\x86_64-8.1.0-release-posix-seh-rt_v6-rev0\\mingw64\\bin\\g++.exe",
            "args": [
                "-fdiagnostics-color=always",
                "-g",
                "${file}",
                "-o",
                "${fileDirname}\\${fileBasenameNoExtension}.exe",
                "-I",
                "C:\\Dev\\opencv\\include",

            ],
            "options": {
                "cwd": "C:\\Dev\\x86_64-8.1.0-release-posix-seh-rt_v6-rev0\\mingw64\\bin"
            },
            "problemMatcher": [
                "$gcc"
            ],
            "group": {
                "kind": "build",
                "isDefault": true
            },
            "detail": "Task generated by Debugger."
        }
    ],
    "version": "2.0.0"
}

 CMakeLists.txt

1. choose gcc compile and ensure you have installed the cmake extension. it is more easy to use.

2. after compiling , you can find Build folder in your project , and your execution file is there

cmake_minimum_required(VERSION 3.15)

project(ImageTreatment3)

set(CMAKE_CXX_STANDARD_REQUIRED ON)

set(CMAKE_PREFIX_PATH ${CMAKE_PREFIX_PATH} "C:\\Dev\\opencv")

set(CMAKE_BUILD_TYPE "Debug")

find_package(OpenCV 4 REQUIRED)
include_directories(${INC_DIR})
link_directories(${LINK_DIR})

aux_source_directory(${PROJECT_SOURCE_DIR} SRC_LIST)
add_executable(${PROJECT_NAME} ${SRC_LIST})

#OpenCV Lib, 如果添加target_link 后cmake 报警错误CMP0111
target_link_libraries(${PROJECT_NAME} PRIVATE ${OpenCV_LIBS})
