Ok, so it seems like no matter what I put for the path, it always creates the libraries in the directory pendertools is located.
It's called PenderAndroidLibrary
I can delete it, run ./pendertools -p (no matter what I put here)
it always goes into the pendertools directory. I've tried every which way to do a path, even duplicated your setup (app.zip in root of c, then used c:/app.zip)
