I'm trying to figure out how to use the winapi SetWindowSubclass
On a non-Qt project under MSVC I can use the API by including:
#include <commctrl.h>
#pragma comment(lib, "Comctl32.lib")
I have been trying for hours unsuccessfully to link this lib on my project. I have found these comctl32.lib on my machine:

I tried adding into .pro:
LIBS += -comctl32
LIBS += -comctl32.lib => error: unrecognized command-line option '-comctl32'
LIBS += comctl32
LIBS += comctl32.lib => error: cannot find comctl32: No such file or directory
I copied the one from C:\Program Files (x86)\Windows Kits\10\Lib\10.0.22000.0\um\arm64
and past it on a new folder under C:\Qt\Libs
LIBS += C:\Qt\Libs => error: cannot find C:\Qt\Libs: Permission denied
LIBS += -L"C:\Qt\Libs" => this didn't throw any of the errors from above, but now I have these compiler error:
.pro
