Non-portable path to file warning. Why?

Hello all!
Started seeing this message:

/Users/alexandr/Projects/build-Desktop_Qt_5_15_2_clang_64bit-Debug/moc_shttpreplyuserlogin.cpp:10: warning: non-portable path to file '"../../DataStorage/DataModels/HTTPReply/shttpreplyuserlogin.h"'; specified path differs in case from file name on disk [-Wnonportable-include-path]
moc_shttpreplyuserlogin.cpp:10:10: warning: non-portable path to file '"../../DataStorage/DataModels/HTTPReply/shttpreplyuserlogin.h"'; specified path differs in case from file name on disk [-Wnonportable-include-path]
#include "../../DataStorage/DataModels/HTTPreply/shttpreplyuserlogin.h"
         ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
         "../../DataStorage/DataModels/HTTPReply/shttpreplyuserlogin.h"

Why is that?

in *.pro file:

INCLUDEPATH += $$PWD/DataModels/HTTPReply

in *.h:

#include <shttpreplyuserlogin.h>

Everything works fine. Just this warning. Is it Qt bug?

No it's not a Qt bug. (The message isn't even generated by Qt, it's generated by your compiler.)

If you read the message it tells you why the path is non-portable, doesn't it?

specified path differs in case from file name on disk [-Wnonportable-include-path]

Will work under e.g. Windows, will not work under e.g. Linux. Hence "nonportable".

And it tells you what to do about it: either switch off the -Wnonportable-include-path warning, or (better) change your include statement or the case of the file/path name on disk to match each other.
