why vs code build cmake project output Directory auto add auto ${buildType}

### Brief Issue Summary

setting.json
`{
"security.workspace.trust.untrustedFiles": "open",
"cmake.configureOnOpen": true,
"cmake.showOptionsMovedNotification": false,
"explorer.confirmPasteNative": false,

output.log
`[build] Auto build dll exports
[build] Automatic MOC and UIC for target image_send
[build] rpc_client.vcxproj -> ..\out\Debug\ui\bin\Debug\rpc_client.dll`

output path: "..\out\Debug\ui\bin\Debug\rpc_client.dll"
how to change output path "..\out\Debug\ui\bin\rpc_client.dll" ?

### CMake Tools Diagnostics

### Debug Log

### Additional Information

_No response_

Start with the reported settings.json, especially cmake.buildDirectory, and compare it with the output.log path for rpc_client.dll. Trace how the CMake Tools configuration produces the duplicated Debug directory, then verify that the generated output ends at ..\out\Debug\ui\bin\rpc_client.dll.
