2.8.0 issues with building

[fordfrog]

Description of the bug

on gentoo linux (with boost-1.85.0) there are some missing includes that prevent compilation. we also had problem with linking prusaslicer because of missing libcrypto. here are the two patches that we use to evade those issues (i'm not sure they're correct though):
https://github.com/gentoo/gentoo/blob/master/media-gfx/prusaslicer/files/prusaslicer-2.8.0-missing-includes.patch

I had to patch the 2.8.0 release the same way for nixos
