This prefix is wrong. If you want to build plugins like the Debian
packages do, just use the same dir-related flags for configuring:

https://salsa.debian.org/claws-mail-team/claws-mail/-/blob/master/debian/rules#L20

Anyway, keep reading...

You need to be root to install stuff on system directories. You missed
the "sudo" bits that Paul mentioned. But if you're puzzled by this error
I'm not sure you should be installing things on system directories as
root ;-)

Safer would be to install the plugin to a directory in your home folder
(e.g.: --prefix=/home/user/myclawsplugins) and load it from the folder
created by make install under it. That doesn't require root and chances
you break your system is zero. Note that Claws Mail allows loading
plugins from any directory, not just the system wide folder.
