Yes, it’s possible to set a global path to your JUCE modules via the “Global Search Paths…” menu item under either “Projucer” (Mac) or “File” (Windows and Linux):
Once this has been set, you can make all of the modules in a project use this global path by selecting “Set all modules to use global paths” from the modules settings page here:
We’re currently updating the tutorial projects and, after this update, they will all use the global paths by default. However for the time being, I believe most (if not all) of the tutorials have the modules path set to ../../JUCE/modules so if you place your tutorials inside a directory next to your main JUCE directory like this:
it should just work.
