[REG 5.14.0 -> 5.14.1] zlib / QtZLib is missing in Qt MSVC release

Hello!
My library project uses minizip with zlib and it's unfortunately missing in the Qt 5.14.1 MSVC release.
This is different to other Qt versions and other 5.14.1 targets (e.g. gcc,mingw) - required headers are present there, as well building projects work there.

TL;DR: zlib was there and now is missing for MSVC since Qt 5.14.1.
Can Qt for MSVC please be compiled again with zlib and so zlib added again?
Affected: msvc2015_64, msvc2017, msvc2017_64

Details

Building minizip fails due missing header file zlib.h.

Search for zlib.h. There for MSVC Qt 5.14.0, but not Qt 5.14.1.
Notice: There is a complete installation with all MSVC targets in qt_sdk/5.14.1/.

Build error. I tried to find a solution, in the thought that maybe just the 5.14.1/msvcX/include/QtZlib/X.h files are missing.
So copied them over from 5.14.0. But another compile error is the result, (can not find zlib lib file).

Let me know if there are any questions or more information required.
Thanks!
