i get this error when i install gromacs ben@ben-System-Product-Name:~/gromacs-2023.3/build$ cmake … -DGMX\_BUILD\_OWN\_FFTW=ON -DREGRESSIONTEST\_DOWNLOAD=ON – GPU support with OpenCL is deprecated. It is still fully supported (and recommended for AMD, Intel, and Apple GPUs). It may be replaced by different approaches in future releases of GROMACS. CMake Error at cmake/gmxManageOpenCL.cmake:51 (message): OpenCL is not supported. OpenCL version 1.2 or newer is required.
