OpenCL can't see drivers on ubuntu

I'm trying to setup opencl for C++ development in ubuntu(22.04) but when I run clinfo I'm geting the following output:

root@turgut-N56VZ:/etc/OpenCL/vendors# clinfo
Number of platforms                               1
  Platform Name                                   Clover
  Platform Vendor                                 Mesa
  Platform Version                                OpenCL 1.1 Mesa 22.0.5
  Platform Profile                                FULL_PROFILE
  Platform Extensions                             cl_khr_icd
  Platform Extensions function suffix             MESA

  Platform Name                                   Clover
Number of devices                                 0

NULL platform behavior
  clGetPlatformInfo(NULL, CL_PLATFORM_NAME, ...)  Clover
  clGetDeviceIDs(NULL, CL_DEVICE_TYPE_ALL, ...)   No devices found in platform [Clover?]
  clCreateContext(NULL, ...) [default]            No devices found in platform
  clCreateContextFromType(NULL, CL_DEVICE_TYPE_DEFAULT)  No devices found in platform
  clCreateContextFromType(NULL, CL_DEVICE_TYPE_CPU)  No devices found in platform
  clCreateContextFromType(NULL, CL_DEVICE_TYPE_GPU)  No devices found in platform
  clCreateContextFromType(NULL, CL_DEVICE_TYPE_ACCELERATOR)  No devices found in platform
  clCreateContextFromType(NULL, CL_DEVICE_TYPE_CUSTOM)  No devices found in platform
  clCreateContextFromType(NULL, CL_DEVICE_TYPE_ALL)  No devices found in platform

ICD loader properties
  ICD loader Name                                 OpenCL ICD Loader
  ICD loader Vendor                               OCL Icd free software
  ICD loader Version                              2.2.14
  ICD loader Profile                              OpenCL 3.0

I can't use it in programs because it says No devices found in platform. When I go to my vendors folder I can see mt .so files present there.

root@turgut-N56VZ:~# cd /etc/OpenCL/vendors/
root@turgut-N56VZ:/etc/OpenCL/vendors# ls
intel.icd  mesa.icd  nvidia.icd
root@turgut-N56VZ:/etc/OpenCL/vendors# ls -la

drwxr-xr-x 2 root   root   4096 Ara  2 09:31 .

/usr/local/lib/libigdrcl.so
root@turgut-N56VZ:/etc/OpenCL/vendors# cat nvidia.icd
libnvidia-opencl.so.1

And when I grep to see my drivers I get:

turgut@turgut-N56VZ:~$ lshw -c video | grep driver
WARNING: you should run this program as super-user.
       configuration: driver=nvidia latency=0
       configuration: depth=32 driver=i915 latency=0 resolution=1920,1080
WARNING: output may be incomplete or inaccurate, you should run this program as super-user.

I've tried running these commands to no avail:

turgut@turgut-N56VZ:~$ sudo usermod -a -G video $LOGNAME
turgut@turgut-N56VZ:~$ sudo usermod -a -G render $LOGNAME

And finally these are my device information:

turgut@turgut-N56VZ:~$ sudo lshw -c display

So why can't my opencl detect and use them? What can I do to make it see them? I can import and compile opencl just fine but I get runtime errors saying No devices found in platform.
