I think the problem is that every Juicer project inside the macos build folder, besides the one for the IDE, generate the exact same VST and component.
If I try to build using juicer the only project that works properly is CabbageIDE.jucer, the .app that gets generated works but I can't export because the vst and component files are missing.
I really can't understand why it works for you.
The errors I get from running the script are the following:
clang: error: no such file or directory: '/Users/antoniotari/cabbage/cabbage-2.0.03/Source/Application/CabbageContentComponent.cpp'
clang: error: no input files
/Users/antoniotari/cabbage/cabbage-2.0.03/Source/Audio/Plugins/CsoundPluginProcessor.cpp:112:2: error: unknown type name 'PluginHostType'
