Qt 模块添加

---

cmake中的代码

find_package(Qt${QT_VERSION_MAJOR} REQUIRED COMPONENTSWidgets)

target_link_libraries(examples_rpa PRIVATE Qt${QT_VERSION_MAJOR}::Widgets)

添加依赖库：动态库

link_libraries(链接库文件)

• link_libraries链接库文件:方法一

//这个接口需要放在"add_executable()"前面

//设置库目录路径
set(LIBINCLUDE_OPENCV ${PROJECT_SOURCE_DIR}/lib)
//链接库文件:绝对路径
link_libraries(${LIBINCLUDE_OPENCV}/opencv_img_hash452d.lib 
               ${LIBINCLUDE_OPENCV}/opencv_world452d.lib)

• link_libraries链接库文件:方法二

//这两个接口需要放在"add_executable()"前面

//设置库目录路径
set(LIBINCLUDE_OPENCV ${PROJECT_SOURCE_DIR}/lib)
//添加库目录
link_directories(${LIBINCLUDE_OPENCV})
//链接库文件:相对库目录路径
link_libraries(opencv_img_hash452d.lib opencv_world452d.lib)

target_link_libraries(链接库文件,推荐使用)

• target_link_libraries,链接库文件方法一

//这6个接口需要放在"add_executable()"前面
//设置库目录路径
set(LIBINCLUDE_OPENCV ${PROJECT_SOURCE_DIR}/lib)
//设置库目录
set(LIBINCLUDE_OPENCV ${PROJECT_SOURCE_DIR}/lib)
add_library(opencv_img_hash452d STATIC IMPORTED)
set_property(TARGET opencv_img_hash452d PROPERTY IMPORTED_LOCATION
    ${LIBINCLUDE_OPENCV}/opencv_img_hash452d.lib)
add_library(opencv_world452d STATIC IMPORTED)
set_property(TARGET opencv_world452d PROPERTY IMPORTED_LOCATION
    ${LIBINCLUDE_OPENCV}/opencv_world452d.lib)

//这1个接口需要放在"add_executable()"后面
//链接库文件
target_link_libraries(example_opencvcpp PRIVATE
     opencv_img_hash452d opencv_world452d
   )

• target_link_libraries,链接库文件方法二

//这1个接口需要放在"add_executable()"前面
//设置库目录路径
set(LIBINCLUDE_OPENCV ${PROJECT_SOURCE_DIR}/lib)

//这1个接口需要放在"add_executable()"后面
//链接库文件
target_link_libraries(example_opencvcpp PRIVATE
     ${LIBINCLUDE_OPENCV}/opencv_img_hash452d.lib
     ${LIBINCLUDE_OPENCV}/opencv_world452d.lib

全局宏

---

//定义全局宏
add_definitions(-DDEF_OPEN_MACRO)

设置变量

---

#设置库目录路径
set(LIBINCLUDE_OPENCV ${PROJECT_SOURCE_DIR}/lib)

打印日志

---

基本的日志

//打印日志
message(STATUS PROJECT_SOURCE_DIR   =  ${PROJECT_SOURCE_DIR})

日志:get_directory_property(获取LINK_DIRECTORIES的值)

//打印日志:get_directory_property,设置的库目录
get_directory_property(result LINK_DIRECTORIES)
message("result: ${result}") # result: /C;/B;/A

日志:get_target_property(获取targer变量的属性)

// #target_link_libraries,链接库文件方法一
// ##设置库目录
// #add_library(opencv_img_hash452d STATIC IMPORTED)
// #set_property(TARGET opencv_img_hash452d PROPERTY IMPORTED_LOCATION
// #    ${LIBINCLUDE_OPENCV}/opencv_img_hash452d.lib)
// #add_library(opencv_world452d STATIC IMPORTED)
// #set_property(TARGET opencv_world452d PROPERTY IMPORTED_LOCATION
// #    ${LIBINCLUDE_OPENCV}/opencv_world452d.lib)
// ##链接库文件
// #target_link_libraries(example_opencvcpp PRIVATE
// #     opencv_img_hash452d opencv_world452d
// #    )
//打印日志:get_directory_property(获取targer变量的属性)
get_target_property(result opencv_world452d IMPORTED_LOCATION)
message("result: ${result}") # result: /C;/B;/A

设置try不中断程序

---

//设置编译参数
add_definitions(/EHa)
string(REGEX REPLACE "/EHsc" "" CMAKE_CXX_FLAGS ${CMAKE_CXX_FLAGS})
