There will be no longer new builds made available of PCSX2 in the Xservers debian repository because the useful cmake presets have been removed from it which really made big difference in how much less complex it was to compile.
The current build in the Xservers debian repository works as long as it does and when it doesn't anymore then it won't and i'm not making new build.
EDIT: the presets seem to still exists but undocumented (no mention in docs) so not sure if they work or not but in any case the build is broken because finding one of the dependencies fail no matter what.
