Error when building the release version with MinGW

[Limaaron]

If we build a library:

1. cmake -G "MinGW Makefiles" -B build
2. mingw32-make Work!

But if we build:

1. cmake -G "MinGW Makefiles" -B build -DCMAKE_BUILD_TYPE=Release
2. mingw32-make It doesn't work :D

@Limaaron - PTAL if the fix https://github.com/kuba--/zip/pull/273 works for you

We can add some if-s for cmake to avoid building with -Werror flag.

WDYT?

it's possible, but I hope there won't be any problems with it. in any case, I will let you know if there is ever a problem with this :)

I found the root of the problem

miniz.h

4910: #elif defined(__MINGW32__) || defined(__MINGW64__)
4911: #include <windows.h>
4912: #ifndef MINIZ_NO_TIME
4913: #include <sys/utime.h>
4914: #endif

windows.h -> winbase.h -> fileapi -> miwindef.h -> #define MAX_PATH 260

zip.c

39: #include "miniz.h"
40: #include "zip.h"

this interrupts the definition inside the zip.h MAX_PATH

This is not works...

This is not a solution. Because disable this validation on the release project may add more issues with app ...
