what to do with the copy to the LIB file request

[technologist]

I have a linux project with a number of files and instructions. Its all pretty explanatory except:

->Copy libArduCamLib.so libusb-1.0.so to /lib folder

In Linux is there an established /lib folder I copy to or do I create a new LIB folder for it and if so, where?

On Debian and Ubuntu it's /usr/lib.

[keskiverto]

Do they have /usr/local/lib too?

(At least on some distros the /usr/local/* are for unmanaged/source installs.)
