For the Qt version- Qt 5.12.2(MSVC 2015 64-bit)
for the compiler , on android- Android Clang and on the desktop -mingw7.3.0

This doesn't make sense as you can't use Qt 5.12.2(MSVC 2015 64-bit) with CLang or MinGW as compiler!
For Qt 5.12.2(MSVC 2015 64-bit) you need MSVC 2015 64-bit compiler (2017 should work as well).

Here is a screenshot, think I made a mistake the other time, I was using the qt cmd to check for my qt version

[SGaist]

Did you get zlib built with MinGW then ?

[Abdulmueez]

Hmmm, the guide said nothing about that, am I to follow the same steps as the build for the extra cmake modules?
Sorry if it sounds like a beginner question

[SGaist]

You should at least check that the architecture of your zlib dll matches the architecture of the Qt version you are using.

Otherwise, check the zlib sources for build instructions.

Checked through the readme, it's also using mingw

  Compiler:
    i686-w64-mingw32-gcc (GCC) 4.5.3
  Library:
    mingw64-i686-runtime/headers: 3.0b_svn5747-1
  Build commands:
    i686-w64-mingw32-gcc -c -DASMV contrib/asm686/match.S
    i686-w64-mingw32-gcc -c -DASMINF -I. -O3 contrib/inflate86/inffas86.c
    make -f win32/Makefile.gcc PREFIX=i686-w64-mingw32- LOC="-mms-bitfields -DASMV -DASMINF" OBJA="inffas86.o match.o"
   Finally, from VS commandline (VS2005 or higher):
    lib -machine:X86 -name:zlib1.dll -def:zlib.def -out:zdll.lib

Right it's a C library, however it looks like built for 32bit and you are using a 64bit build of Qt.

[Abdulmueez]

Went directly to the website to get a version that uses 64 bit, didn't seem to be such. Checked their FAQ and found this

Will zlib work on a 64-bit machine? 
Yes. It has been tested on 64-bit machines, and has no dependence on any data types being limited to 32-bits in length. 

So, should I replace the version I have with the latest one on their site or I should keep on using the one from the guide?

You have to use a 64bit version, so get one, or build it by yourself if there is no official build.

So, I just succeeded in getting rid of the error by using the following

mkdir C:\Builds\zlib; cd C:\Builds\zlib
cmake -G "Visual Studio 16 2019" -A x64 D:\Downloads\zlib-1.2.8\
cmake --build .

and then going to my cmake gui to include the zlib directory and the bzip2 directory.
Also, the versions from the guide I was using was outdated, I had to download new versions of ZLIB and BZIP2
