vscode+cmake+opencv3 编译、断点调试cpp 子文件需要opencv lib

时间紧迫，草率做了个笔记，主要内容就是CMakeLists.txt和json的配置，其他的cpp由于涉及到个人项目，不便公开，见谅。

文件结构

bin：可执行文件更新：可执行文件放在build内
--------opencvTest

build：cmake出的文件 及 可执行文件 ///updated

include：头文件
--------include/calWear.hpp
--------include/match.hpp
--------include/mouse.hpp

src：源文件 source
--------src/calWear.cpp
--------src/CMakeLists.txt
--------src/match.cpp
--------src/mouse.cpp

CMakeLists.txt
HullDetect.cpp///这是我的项目文件
opencvTest.cpp///测试文件
templ.jpg///测试文件需要显示的图片

CMakeFiles.txt

根目录下CMakeLists.txt：

CMAKE_MINIMUM_REQUIRED(VERSION 2.6)

# 项目名称
PROJECT(opencvTest)

# 找opencv package----------记得添加这个
find_package(OpenCV REQUIRED) 

set(CMAKE_C_COMPILER "gcc")
set(CMAKE_CXX_COMPILER "g++")
set(CMAKE_CXX_STANDARD 11)

# 根目录/代码路径
aux_source_directory(. DIR_MAIN)

# dubug 模式------------------这个非常重要，否则无法进入断点
set (CMAKE_CXX_FLAGS  "${CMAKE_CXX_FLAGS} -g")

# 添加子目录
include_directories("${PROJECT_SOURCE_DIR}/include")
add_subdirectory(src)

# 编译成可执行文件
set(EXECUTABLE_OUTPUT_PATH ${PROJECT_SOURCE_DIR}/build) 
add_executable(opencvTest opencvTest.cpp)

# 链接hellolib库，注意下面子目录src的CMakeLists
link_directories("${PROJECT_SOURCE_DIR}/lib")
target_link_libraries(opencvTest hellolib)
# 链接opencv库
target_link_libraries(opencvTest ${OpenCV_LIBS})

src目录下CMakeLists.txt

CMAKE_MINIMUM_REQUIRED(VERSION 2.6)

# generate lib
#设置生成lib文件的位置
## SET(LIBRARY_OUTPUT_PATH ${PROJECT_SOURCE_DIR}/lib)  
#代码路径
aux_source_directory(. DIR_SRC)

# 生成库
add_library(hellolib ${DIR_SRC})
# 链接opencv库
target_link_libraries(hellolib ${OpenCV_LIBS})
