fix macOS build (following Projucer changes made in Windows, which removed /Applications/JUCE/modules from its headers). move JUCE headers under source control, so that Windows and macOS can both build against same version of JUCE. remove AUv3 target (I think it's an iOS thing, so it will never work with this macOS fluidsynth dylib).

before closing the older one, because this way both devices can share the same
underlying camera session. Otherwise, the session needs to be close first, and this
is a lengthy process that can take several seconds.
