c/c++语言开发共享升级Xcode 导致Qt无法编译 解决办法

问题：

今天Xcode升级，Qt编译已有的项目出现问题 ：

-1: error: No rule to make target `test2′.  Stop.   

/Users/mac/Qt/5.15.0/clang_64/mkspecs/features/mac/sdk.mk:22: error: *** ^.  Stop.

两行报错信息说的也是不明不白。点击右键，显示输出，得到更多信息：

make: *** No rule to make target `test2′.  Stop.
The platform SDK has been changed from version 10.15.4 to version 10.15.6.
This requires a fresh build. Please wipe the build directory completely,
including any .qmake.stash and .qmake.cache files generated by qmake.
/Users/mac/Qt/5.15.0/clang_64/mkspecs/features/mac/sdk.mk:22: *** ^.  Stop.
17:20:44: 进程”/usr/bin/make”退出，退出代码 2 。
Error while building/deploying project test2 (kit: Desktop Qt 5.15.0 clang 64bit)
When executing step “Make”
17:20:44: Elapsed time: 00:00.

解决办法：

说白了很简单就是因为你升级了Xcode，默认的SDK也变了，我们只需要清掉build缓存文件夹即可，直接删掉，然后重新运行项目即可。
