Unable to open the source file in qt vs2015 "QtWidgets" solution

In theory there are two steps,1.QT VS TOOL To set the version correctly

Note that the location where the version is added is a short path

如上所示,到F:\Qt\Qt5.8.0_32,就行,不需要到F:\Qt\Qt5.8.0_32\bin目标

2.

加环境变量,Otherwise, it is impossible to use this directly as shown in the picture belowqtpath also works,It seems to be adding one laterAdditionalincludeDirectories

如下图所示,You can use environment variables

右键VS项目,属性->C/C++/常规,添加QT的include路径即可.（也可以在VC++set in the directory）

$(Qt_INCLUDEPATH);%(AdditionalIncludeDirectories);$(IncludePath)
