Build: error: ‘unique_ptr’ in namespace ‘std’ does not name a template type

Hi, I tried building from master on Arch Linux, which didn't work because of the botan2 dependency (arch is on botan3). Therefore I tried to build with the botan3 branch, where I get this error:

make: *** [Makefile:69: /tmp/encryptpad_build/deps/libencryptmsg/build/libencryptmsg.a] Error 2

I tried with qt6 branch as well - same error.

By the suggestion, it looks like an easy fix:

note: ‘std::unique_ptr’ is defined in header ‘’; this is probably fixable by adding ‘#include ’
9 | #include "emsg_utility.h"
+++ |+#include

Ticket #140 states that encryptpad has been updated to qt6 and botan3 on the qt6 branch, download the repo and git checkout qt6
