QT的cmake项目工程配置-CFANZ编程社区

QT的项目工程默认使用的是qmake,这本来也没什么问题。但是由于要用到vcpkg这个工具来管理第三方库，好像这个 vcpkg工具只能在cmake的项目中才能使用。

于是这里记录下QT的cmake工程配置，需要注意的是需要额外配置个项：

-DCMAKE_PREFIX_PATH=D:\Qt\Qt5.10.0\5.10.0\msvc2015\lib\cmake 
-DCMAKE_TOOLCHAIN_FILE=F:\vcpkg\scripts\buildsystems\vcpkg.cmake -Wno-dev

另外需要注意的是，在QT的环境中可以直接运行能出来界面没问题。

在其他环境下，得先记得先打包导出才行! 之前就是忘了这个差点以为代码配置问题。

Qml的打包和QT传统的打包方式也是不同的。

QT的打包可以用这个：

D:\Qt\Qt5.10.0\5.10.0\msvc2015\bin\windeployqt.exe -no-angle -no-opengl-sw test.exe

QML的应用打包，通过cd命令到你的exe存放的地方，并输入下面的命令：

windeployqt  -qmldir   "源码路径"     test.exe   --release

命令执行完后，在你exe生成的目录里生成qt的依赖文件。如果你的源码使用了三方库或者生成了动态链接库，那么需要手动将需要的dll文件复制到目录下，实际运行试试，是不是可以正常运行。

CmakeLists.txt 配置模板如下：

cmake_minimum_required(VERSION 3.12)

project(test VERSION 0.3.19)

#宏定义在这里添加
add_definitions(
        -D_ENABLE_LOGGING
)
