creat new project and report errors

[zemon]

after installed Qt6.8.2 and qt creator,I tried to creat a new project "Qt Widgets Application"
but there are some issues.
one is:
/home/..../Qt6/Qt6Config.cmake
but it set Qt6_FOUND to FALSE so package "Qt6" is considered to be NOT FOUND. Reason given by package: failed to find required Qt componet "Widgets"
expected config file at
"/home/igs/Qt/6.8.2/gcc_64/lib/cmake/Qt6Widgets/Qt6WidgetsConfig.cmake

and In projects->Build&Run ->Build->Build directory .there is a warning：Cmake project configuration failed.No CMake configuration for build type "Debug" found.Check General Messages for more information
