Vscode与Cmake搭配配置opencv使用

vscode与Cmake基本使用

下载插件
Ctrl+Shift+p打开VSCode的指令面板，然后输入cmake:q，VSCode会根据输入自动提示，然后选择CMake: Quick Start
选择编译器
根据提示输入项目名称
选择可执行文件
编译项目
- 方式一：执行命令
```
cd build
cmake ..
```
- 方式二： VSCode提供了更便捷的方式（点击底部的Build）

opencv 配置

基于Cmake方式

方法一：

cmake文件内容

message(STATUS "Setting up OpenCV libs for: ${CMAKE_CURRENT_SOURCE_DIR}")
message(STATUS "source dir: ${CMAKE_SOURCE_DIR}")
include_directories("D:/MyWork/tools/dl_deploy_cpp-main/include/opencv4/")
link_directories("D:/MyWork/tools/4.8.1/")
set(OpenCV_LIBS opencv_world opencv_3rdparty)
message(STATUS "Setting up OpenCV libs done! OpenCV_LIBS:+[${OpenCV_LIBS}]")

txt文件内容

cmake_minimum_required(VERSION 3.0.0)
project(demo VERSION 0.1.0 LANGUAGES C CXX)
add_executable(demo main.cpp)


# set(CPACK_PROJECT_NAME ${PROJECT_NAME})
# set(CPACK_PROJECT_VERSION ${PROJECT_VERSION})
# include(CPack)


option(INCLUDE_OPENCV "package OpenCV into dl_deploy." ON)
message(STATUS "INCLUDE_OPENCV: ${INCLUDE_OPENCV}")

# opencv, add library
if (INCLUDE_OPENCV)
    include(opencv.cmake)
endif ()

message(STATUS "libs is: ${OpenCV_LIBS}")

if (INCLUDE_OPENCV)
    target_link_libraries(${PROJECT_NAME} ${OpenCV_LIBS})
endif ()

cmake LINK_DIRECTORIES不起作用,找不到lib文件，原因是ADD_EXECUTABLE出现在LINK_DIRECTORIES之前。正确的做法是将LINK_DIRECTORIES放在ADD_EXECUTABLE之前。

方法二：

cmake_minimum_required(VERSION 2.8)

project(test)

set(DEFAULT_CXX_STANDARD 11)

set(OpenCV_DIR  D:/opencv/opencv3.4.6/opencv/build/x64/vc15/lib/)#库路径你自己换成你电脑上的

find_package(OpenCV REQUIRED)

include_directories(${OpenCV_INCLUDE_DIRS})

add_executable(main ${PROJECT_SOURCE_DIR}/main.cpp)

target_link_libraries(main  ${OpenCV_LIBS})

基于vscode配置

无需编译快捷版

问题解决：

找不到链接库，系统环境变量添加
opencv无法定位程序输入点于动态链接库 MinGW版本与编译opencv时的版本不对应
