dolphin/Source/Core/VideoCommon/Src/OpenCL/OCLTextureDecoder.cpp
Orphis c2e32371f6 Refactor and prepare the OpenCL texture decoder for decoding textures to RGBA format required by DX11.
Fix the decoder codepath when OpenCL is enabled and the DX11 plugin is used.
Added the DX11 plugin to the Dolphin project dependencies.
