今天刚好想用QT中的一个例子，玩一下，却发现一大堆错误，无论选择什么编译器总是提示
‘

Running Windows Runtime device detection.
No winrtrunner.exe found.
Running Windows Runtime device detection.
No winrtrunner.exe found.

D:/Qt/Qt5.14.1/5.14.1/android/mkspecs/features/toolchain.prf(76): Variable QMAKE_CXX.COMPILER_MACROS is not defined.
Project ERROR: failed to parse default search paths from compiler output

如下所示

我看了一下，那个构建和运行的项目目录，是不对的

把项目目录改为当前目录就行了，编译成功！！！
