Describe the bug

root@hp-xw4400:~# AmneziaVPN
Incompatible processor. This Qt build requires the following features:
    sse4.1 sse4.2 popcnt
Aborted

Desktop (please complete the following information):

  • OS: Debian 13

Additional context I can't beleive that VPN GUI really requires CPU instruction set more recent than e.g. CAD software. ;-) While AWG engine doesn't require it. See issue #2592. Please, compile Qt with proper flags.
