QtAV, Qt version and platform

Not sure QtAV version, git clone master branch on 10/29/2022
commit fdc613d
Qt version: 5.15.5
Windows 10, msys2/ming32

or commit id if not using release version

Reproduction steps

msys2 and mingw32 path are: C:\msys64\mingw32
qtav source code path is: C:\msys64\home\QtAV
I open a msys2 terminal windows with administrator role
and navigate to the folder: C:\msys64\home\QtAV\msys2
issue a command: makepkg-mingw -sCLf

I downloaded dependencies from https://sourceforge.net/projects/qtav/files/depends/QtAV-depends-windows-x86+x64.7z/download
and unzip and place files in /include and /lib to c:\msys64\mingw32\include and c:\msys64\mingw32\lib seperately and do:
export CPATH=c:/msys64/mingw32/include:$CPATH
export LIBRARY_PATH=c:/msys64/mingw32/lib:$LIBRARY_PATH
export LD_LIBRARY_PATH=c:/msys64/mingw32/lib:$LD_LIBRARY_PATH

Expected behavior

QtAV modules will be generated and I can use it in a qml project

Actual behavior

make failed, the details are as below (part):
