Hi, set build environment from scratch and since then Blender does not recognize Nvidia GPU anymore in user preferences.
I have a lot of features disabled, don´t need it or does not compile.

I have no idea where I have to look to get it to work again.
Thanks, mib
You should never edit your CMakeLists.txt, once you run cmake all variables will be in your CMakeCache.txt in your build folder (which is also the file you should have posted), you can change them by passing -DSOMEVAR=somevalue to your cmake invocation. But never directly in CMakeLists.txt
beyond that, i’m guessiing you are looking to run make release in the blender source folder to get the release presets.

Hi, I work with Cmake Gui but will look in to DWORDS
Make lite is working but make release does nothing
make release
make: Für das Ziel „release“ ist nichts zu tun.
Will delete cache and start again.
Thanks for the help, mib

Hm, same result, but make no sense anyway as make full does not compile on my system either, therefor I disable so many libs and features.

Allright then just make sure you turn WITH_CYCLES_CUDA_BINARIES on and you should be good to go.
The binyries would not help, I cant select Cuda device in user preferences.
Cheers, mib
Compiling Blender on Linux is kind of a nightmare, even on Ubuntu. But you don’t need to compile the cubins. When you render with CUDA (if it’s recognised in user prefs) it will compile the cubins on the fly. Why your card is not listed is probably a driver problem. If you use Timeshift (which you should as Linux bricks himself even with simple security updates sometime) you can just restore a state where it was working.
we worked it out on irc, the cuda toolkit wasn’t isntalled
Hi Dodo! I have a similar problem, but on Linux MINT. I’m trying not to up a new topic yet. I’m not a tech and I’m just helping mine to find an answer, so we can install CUDA but Blender 2.82 doesn’t recognize it, as WIN does [Dual - I’m trying to migrate for Linux]. Can u help me? If so, what info do u need?
Not much i can do with the information given (which is basically “it doesn’t work”), i’d probably start by running blender with the --debug-cycles switch and see what that says about CUDA and take it from there.
Tks Dodo, but I could solve the problem already! 
hey , I’m very new to blender and blender development I’ve being using the blender build de, but i didn’t change any codes or anything . but it doesn’t detect my NVEDIA 3060 GPU on my laptop. but the Blender version i previously directly downloaded from the website it doesn’t have any problem detecting the GPU. how to fix this 
Thank you so much for the quick respond. i will check that out
