E:\vcpkg_folders\qt6\installed\x64-windows-static\include\jpeglib.h(97): error C3646: 'sent_table': unknown override specifier
E:\vcpkg_folders\qt6\installed\x64-windows-static\include\jpeglib.h(97): error C4430: missing type specifier - int assumed. Note: C++ does not support default-int

The reason is that jmorecfg.h and jconfig.h between Qt and an externally installed Jpeg does not agree. I added a patch which makes it work for vcpkg and also added the installed jconfig.h and jmorecfg.h which are installed by libjpeg-turbo's cmake build.
