How to install OpenCL?


I have an AMD RX 580 2048SP graphic card, which works fine, but I also have some application like Mandelbulber (3D fractal) which use OpenCL, actually it's quite slow as the different software able to use OpenCL, use only the processor of my computer, I downloaded the .deb from AMD, but I don't want to install all the thing, just the OpenCL, how I do that?

I'm on Ubuntu-MATE 20.04.5 LTS
