Hello I am attempting to install gromacs for the first time and I am ecountering this error. “-- Selecting Windows SDK version 10.0.22621.0 to target Windows 10.0.22631.  
– GPU support with OpenCL is deprecated. It is still fully supported (and recommended for Apple GPUs). Please use CUDA for running on NVIDIA GPUs and SYCL for running on Intel and AMD GPUs.  
– Could NOT find OpenCL (missing: OpenCL\_LIBRARY OpenCL\_INCLUDE\_DIR)  
CMake Error at cmake/gmxManageOpenCL.cmake:55 (message):  
OpenCL not found.  
Call Stack (most recent call first):

I do not know what to do, does anyone have a solution?
