Certainly not brushed off as nonexistent (see my post here). If VST compilation is really broken that’d be a very worrying bug. It’s just highly unlikely because none of us can reproduce it here. In 99.9% of the cases it’s because any of those:
- the VST SDK path is wrong in the Projucer’s global preferences
- the VST SDK path is wrong in the Projucer’s Xcode exporter preferences for your project
- you don’t have the correct version of the VST SDK (the one to use is 3.6.5 from 3rd-Party Developers Support & SDKs | Steinberg for both VST2 and VST3)
- your VST SDK may be somehow corrupted or not contain the file you try to include
- you didn’t re-save your project from the Projucer so it still has some wrong paths
- something specific to your project, therefore please also test it with the JuceDemoPlugin (
JUCE/examples/audio plugin demo
)
Let me illustrate this in a screenshot:
