vs qt项目互转

用工具QT VS TOOL生成.pro，执行convert，移动ui_QtGuiApplication.h，在pro文件添加greaterThan(QT_MAJOR_VERSION, 4): QT += widgets这句话。

如果你加上greaterThan(QT_MAJOR_VERSION, 4): QT += widgets，还是几十上百个的报错，项目-右击-清除-执行qmake，然后构建或者运行都可以。

在 D:\QT\Qt5.9.0\5.9\msvc2015\mkspecs\common\msvc-version.conf

加入QMAKE_MSC_VER = 1900

打开Qt for Desktop

进入到pro文件目录

输入qmake -r -tp vc

pro中加入CONFIG+=suppress_vcproj_warnings
