Hello,
Move/copy the controlP5 folder to the path where your PERSONAL Processing folder resides i.e. not where you installed/unzipped Processing itself. When you launch Processing it creates a Processing user folder typically in ..MyDocumentsProcessing on Windows and homeuser on Linux. Inside this folder there is a Processinglibraries folder on Windoze and/or sketcheslibraries folder on Linux (or something like that). This is where the controlP5 folder needs to reside and not where the Processing bins/libs reside.
Also, you will probably encounter an error. Please read my most recent post because I am about to edit it with my findings.
Cheers,
ZG
