Package: qgis Version: 3.10.14+dfsg-1 Severity: normal Dear Maintainer,
I tried to enable OpenCL acceleration on QGIS options menu by going to "Settings -> Options -> Acceleration" and toggling the "Enable OpenCL Acceleration" menu option. At first, this failed with a message that it could not find the appropriate drivers. After installing the `mesa-opencl-icd` package, which enabled OpenCL for my GPU in other applications, QGIS still failed to detect the drivers. After some digging, I found that QGIS was trying to dlopen `libOpenCL.so` in several locations, but the `ocl-icd-libopencl1` package installed by `mesa- opencl-icd` only provided `libOpenCL.so.1`. Symlinking `libOpenCL.so.1` to `libOpenCL.so` fixes the issue, and this is provided by the `ocl-icd-opencl-dev` package. I suggest that this package is either added to the QGIS package suggestions or the error message within QGIS is updated to suggest installing it.
