Beginner Question - not seeing example VSTs in my Plug-Ins/vst3 folder

I’ve followed the basic tutorial but I’m not seeing the plugins appear in the VST folder after running the following.

// go in to the folder where you extracted the VST 3 SDK
mkdir build
cd build
/Applications/CMake.app/Content/bin/cmake -G "Xcode" "../vst3sdk"

Which folder did you check? The plug-ins should be in $HOME/Library/Audio/Plug-Ins/VST3/.
Did you build the project via cmake --build . ?
You should be able to start a DAW supporting VST3 after building and loading one of the example in the SDK.
