sounds plausible actually. How do I use external Zlib though? I mean Qt
does not seem to have a zlib.lib somewhere in the kit, so including Qts
zlib.h does not make sense then either. Would I have to compile my own
zlib.lib separately and use the corresponding zlib.h? Then I would also not
need QtZlib, indeed I would also get the same error if I compiled a
different zlib.lib version then Qts zlib.h... As I already wrote, the whole
thing seems kinda suspicious. The variable is called
_Qt6ZlibPrivate_OWN_INCLUDE_DIRS, "private" suggests like it is just for
Qt, not for the application which uses Qt (like LyX), so why does it
include it in LyX in the first place?
I mean I don't know, as I wrote my commit was a workaround rather than a
solution...
