dependency of Qt6Core5Compat. Since we have
include_directories(${Qt6Core5Compat_INCLUDE_DIRS})
https://git.lyx.org/?p=lyx.git;a=blob;f=CMakeLists.txt;h=4a9c428d4a48c838f9e9cd61fab59c46a330b1b3;hb=HEAD#l837
It includes those dirs. I don't know it does seem kinda suspicious to me,
because actually Qt forces everyone who needs Core to use QtZlib with that,
but I can't evaluate that. I just tried to add a
list(REMOVE_ITEM Qt6Core5Compat_INCLUDE_DIRS
"C:/Qt/6.4.1/msvc2019_64/include/QtZlib")
just before that include_directories command and it works
perfectly fine, everything compiles and runs as it should. With Qt5 it
works fine because we don't include any dirs there but we do with that
compatibility module.
What we could do is use this command:
list(REMOVE_ITEM Qt6Core5Compat_INCLUDE_DIRS
"${CMAKE_PREFIX_PATH}/include/QtZlib")
but it would rather be a workaround than a solution. Any thoughts?
