CMakeLists.txt for GDK backend

[rbratta]

I am a registered Xbox developer and I want to build FSR1 and FSR3 for GDK backend. To do this, I copied the AMDTK\fidelityfx\src\backends\gdk directory (from October 2024 GDKX samples) to the sdk\src\backends directory and then started the CMake generation step with the following command: cmake.exe -S sdk -B _build\scarlett -D FFX_API_BACKEND=GDK_SCARLETT_X64 -D FFX_FSR1=ON -D FFX_FSR3=ON. But CMake (of course) gives an error (due to the add_subdirectory(${FFX_SRC_BACKENDS_PATH}/gdk) statement) because there is no CMakeLists.txt in sdk\src\backends\gdk. Where should I find that file? Do I have to write it by myself?
