关于编译安装qt源码后无法使用cmake产生Makefile文件的问题
问题：执行cmake命令输出Makefile文件
报错：Could not find a package configuration file provided by “QT” with any of the following names
Qt6Config.cmake
qt6-config.cmake
Qt5Config.cmake
qt5-config.cmake
解决方法：在qt编译后的目录下找到 Qt5Config.cmake文件，设置环境变量Qt5_DIR为当前目录。例如D:qt-5.15.3-windows-x64-msvclibcmakeQt5
