I just put the cam_xyz into ColorMatrix1 and set the illuminant1 to D65.
The DNG output color is slightly off but acceptable.
I'm not sure if libraw can do this. Take the PixelShift2DNG application as an example, that one is built around libraw but only supports a few cameras, the ColorMatrix1 field can be easily copied from Adobe DNG Converter results.
Well, that's one possible solution, convert the images using Adobe DNG Converter first, then you have it.
