Qt 6.8.1 is also available now.

By the way the current Qt version provided in appveyor's Windows image (Qt 6.7.2) is affected by QTBUG-126775 (cause incorrect behavior with windeployqt), so if appveyor would like to keep providing 6.7, it's suggest to upgrade to 6.7.3 as well.

AppVeyor has Qt 6.8.0 now, however I have trouble to build a package which worked previously with Qt 6.7.2

I got following error:

-- Could NOT find Qt6Core5Compat (missing: Qt6Core5Compat_DIR)
CMake Error at CMakeLists.txt:83 (find_package):
  Found package configuration file:
    C:/Qt/6.8.0/msvc2022_64/lib/cmake/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 component "Core5Compat".
  Expected Config file at
  "C:/Qt/6.8.0/msvc2022_64/lib/cmake/Qt6Core5Compat/Qt6Core5CompatConfig.cmake"
  does NOT exist

Qt 6.8.1 exists already. When I install it on my computer, I have there this file:
C:\Qt\6.8.1\msvc2022_64\lib\cmake\Qt6Core5Compat\Qt6Core5CompatConfig.cmake

I don't know why the Qt6Core5CompatConfig.cmake is not there in AppVeyor's Qt 6.8.0 .

I am suggesting to upgrade to Qt 6.8.1 anyway.

By the way, the mingw1310_64 toolchain also is missing which seems to be used by Qt 6.8's MinGW version.

Qt 6.8 has some more significant differences in terms of components and folder structure that weren't immediately apparent. New images with 6.8.1 will be coming that hopefully address these issue soon.
