[qttools] Install error.

[reitowo]

Qt 6.7.0 doesn't handle CMake scripts properly at install command. When using qt_generate_deploy_app_script in my CMakeLists and install, it can't find qtpaths.exe. It is trying to find under vcpkg_installed/x64-windows/bin but it is in vcpkg_installed/x64_windows/tools/Qt6/bin. Also, when setting the qtpaths manually to correct path, it also trying to find all debug dlls under vcpkg_installed/x64-windows/bin instead of vcpkg_installed/x64_windows/debug/bin.

At least 6.4.3 version was working normally.

Qt really just don't like vcpkg's model, huh?

[Neumann-A]

can you give me an expanded trace with --trace-expand?

Probably an easy fix by adjusting the script

[reitowo]

--trace-expand which command this arg is apply to?

it also trying to find all debug dlls under vcpkg_installed/x64-windows/bin instead of vcpkg_installed/x64_windows/debug/bin.

For debug libs it needs to use windeployqt.debug.bat. The target should be setup accordingly. Did you call find_package with CoreTools ?

[Neumann-A]

And for testing you can just manually edit the installed tree with the patch above. That avoids reinstalling all of qt.

[reitowo]

The patch works! Thanks. Would you submit a PR?
