Hi, I am building my Qt project with Visual Studio Generator using the following command `cmake --build . --config Release`. But When I run my program, it says the uucrtbased.dll and vcruntime140d.dll were not found? So since I built the project with Release configuration , why it is still asking me for debugging version of those DLLs?  
**I can tell the Qt part bundle is correct, only the Microsoft runtime part is not**.  
Thanks for the help

What Qt version are you using?

In case it is relevant, see [this issue](https://gitlab.kitware.com/cmake/cmake/-/issues/22745) which is for a statically built Qt 5.
