創建一個vscode文件

記得一定要創建一個build文件夾，因為cmake編譯過程中產生的中間文件會放到build文件夾中。

打開VScode

配置文件

launch.json

{"version": "0.2.0","configurations": [{"name": "(gdb) Launch","type": "cppdbg","request": "launch",// Resolved by CMake Tools:"program": "${workspaceFolder}/${fileBasenameNoExtension}.out","args": [],"stopAtEntry": false,"cwd": "${workspaceFolder}","environment": [],"externalConsole": true,"MIMode": "gdb","setupCommands": [{"description": "Enable pretty-printing for gdb","text": "-enable-pretty-printing","ignoreFailures": true}]}]
}

c_cpp_properties.json

點擊右下角的Linux，隨后點擊編輯配置（JSON）

或者
Ctrl+Shift+P,輸入C/C++,選擇C/C++: Edit Configurations(JSON)

{"configurations": [{"name": "Linux","includePath": ["${workspaceFolder}/**"],"defines": [],"compilerPath": "/usr/bin/gcc","cStandard": "c11","cppStandard": "c++17","intelliSenseMode": "linux-gcc-x64","configurationProvider": "ms-vscode.cmake-tools"}],"version": 4
}

task.json

點擊終端----配置任務，選擇第一個

{"version": "2.0.0","tasks": [{"label": "make build",//編譯的項目名，build"type": "shell","command": "cd ./build ;cmake .. ;make",//編譯命令"group": {"kind": "build","isDefault": true}},{"label": "clean","type": "shell","command": "make clean",}]
}

配置CMAKE文件

在主目錄下創建一個CMakeLists.txt

cmake_minimum_required(VERSION 3.16)
project(hello)
SET(EXECUTABLE_OUTPUT_PATH ./bin)
set(CMAKE_CXX_STANDARD 11)find_package(OpenCV REQUIRED)
ADD_EXECUTABLE(hello src/test.cpp)
target_link_libraries(${PROJECT_NAME} ${OpenCV_LIBS})

這里筆者調用了OPENCV庫，如果讀者沒有安裝的話，可以將下面兩行注釋掉：

find_package(OpenCV REQUIRED)
target_link_libraries(${PROJECT_NAME} ${OpenCV_LIBS})

終端中運行程序

編寫cpp文件，Shift+Ctrl+B編譯，此時在build/bin中生成一個可執行文件，在終端中運行
