Some .cl files has to be removed with nvidia GPUs
I had to remove some .cl files (soften.cl, highpass.cl, demosaic_ppg.cl) and after that, darktable has been able to use OpenCL (nvidia, cuda etc.)

Strange, now it doesn't work at all. Sorry for misunderstanding btw, I was talking about running Darktable on PC with OpenCL /CUDA/ enabled NVIDIA card. It seems it depends on so many circumstances, fiddling with packages and may be even types of NVIDIA GPUs...
