CMake Qt配置Halcon


下面讲解如何引入Halcon的include和lib

CMakeLists.txt内容

################################# 1、最低CMake版本
cmake_minimum_required(VERSION 3.5)

################################# 2、项目名qtCmake
project(qtCmake LANGUAGES CXX)

################################# 3、set模块
set(CMAKE_INCLUDE_CURRENT_DIR ON)
set(CMAKE_AUTOUIC ON)
set(CMAKE_AUTOMOC ON)
set(CMAKE_AUTORCC ON)
# 设置exe生成路径。喜欢用CMAKE_CURRENT_SOURCE_DIR,指CMakeLists.txt所在的路径
set(EXECUTABLE_OUTPUT_PATH ${CMAKE_CURRENT_SOURCE_DIR}/build/)
# 设置c++语言支持
set(CMAKE_CXX_STANDARD 17)
set(CMAKE_CXX_STANDARD_REQUIRED ON)

################################# 4、查找依赖的Qt文件
find_package(Qt5 COMPONENTS Widgets REQUIRED)
#配置halcon,include、lib目录,具体的lib在target_link_libraries里(注意不加.lib后缀)
#系统环境变量$ENV,也可以换成自己的绝对路径
include_directories("$ENV{HALCONROOT}/include"
                    "$ENV{HALCONROOT}/include/halconcpp")
link_directories("$ENV{HALCONROOT}/lib/$ENV{HALCONARCH}")

################################# 5、生成qtHalcon.exe
add_executable(qtHalcon
    main.cpp
    widget.cpp
    widget.h)
target_link_libraries(qtHalcon PRIVATE Qt5::Widgets halcon halconcpp)

include的意义,include路径后,就不需要#include“一长串路径/HalconCpp.h”
