Hi all, A recent change added OpenCL. Compilation fails on macOS because Apple provides v1.2 (macOS 10.13) while QGIS seems to require v2. Adding a version to FIND_PACKAGE will fix the macOS compile and not use OpenCL. Apple has deprecated OpenCL in favor of its own Metal technology. OpenCL

Hi Anita, Thanks very much for this. I am still lost though. If I replace the sink and add your code I don't get an output in the dialog box - it needs to be a parameter for that to happen right? I found this https://gis.stackexchange.com/questions/282773/writing-a-python-processing-script-with-q

I would say: At plugin load time, check if your other plugins are already loaded. If yes, don't load the processing provider, it's already loaded by the first loaded plugin. You need to use the same provider name (id). So your models won't be broken. Don't forget to update each processing algorit
