If I build an AU plugin with Xcode’s “Legacy Build System” it works - but if I select “New Build System” the build fails with “Command Rez failed with a nonzero exit code” error (that stems from IPlugAU.r).
Why is that? Is there a way to fix or update the IPlugAU.r code for the New Build System?
This does not seem to be an issue with VST2, VST3 or AAX - they build OK using “New Build System”.
BTW - I already checked this: https://github.com/iPlug2/iPlug2/issues/316 and I have the path as shown - but still get the Rez error with New Build System.
