Cmake與QT5初識

以下描述使用外部構建方式
1、創建cmake工程；
2、創建QT設計界面類；例如mainwindow
3、添加上一步創建的文件添加至工程，cmake代碼：
set(SRCLIST main.cpp; mainwindow.cpp; mainwindow.ui; mainwindow.h)
4、添加QT模塊，cmake代碼：
find_package(Qt5Widgets)
target_link_libraries(untitled Qt5::Widgets)
5、設置cmake變量
set(CMAKE_PREFIX_PATH “D:\qtCreator\qtBin\5.13.2\mingw73_64\lib\cmake”)
set(CMAKE_AUTOMOC ON)
set(CMAKE_AUTOUIC ON)
set(CMAKE_AUTORCC ON)

CMAKE_PREFIX_PATH：需添加，否則生成makefile時找不到QT頭文件，改值路徑""需轉義

cmake代碼：

cmake_minimum_required(VERSION 3.1)

project(untitled LANGUAGES CXX)

set(SRCLIST main.cpp; mainwindow.cpp; mainwindow.ui; mainwindow.h)

set(CMAKE_PREFIX_PATH "D:\\qtCreator\\qtBin\\5.13.2\\mingw73_64\\lib\\cmake")
set(CMAKE_INCLUDE_CURRENT_DIR ON)
set(CMAKE_AUTOMOC ON)
set(CMAKE_AUTOUIC ON)
set(CMAKE_AUTORCC ON)

set(CMAKE_CXX_STANDARD 11)
set(CMAKE_CXX_STANDARD_REQUIRED ON)

message(STATUS "Hello word")

find_package(Qt5Widgets)

add_executable(untitled ${SRCLIST})

target_link_libraries(untitled Qt5::Widgets)

備註：外部構建生成QT程序無發直接運行，可通過windeployqt xxx.exe 將QT庫拷貝至exe所在文件夾內。
