Plugin errors on mac 10.14

I am creating plugins in Cabbage (csound) and wanting to import them to FMod (I have tried 3 or 4 different versions) and in all cases I get an error message saying the dylib file cannot be found - but obviously it knows it is there:
00:18:29 Error loading plugin /Users/keith/Desktop/CSoundStuff/MaleVoice.dylib: File not found.

I am wondering if this is an issue with Mac OS 10.14 and higher and if it is, then what can be done to get around it (other than downgrading or switching to Windows)

I have also posted a message on the Cabbage forum

Could you please describe in more detail how you are importing this plugin into FMOD Studio? For example, which plugin directory are you placing the files in?
