exiv2-0.28.5 build on Windows not generating exiv2.dll.

[U4a18]

I use cmake with all dependent libraries built on my own without conan. After exiv2 build I got

LINK : warning LNK4098: defaultlib 'MSVCRT' conflicts with use of other libs; use /NODEFAULTLIB:library [\exiv2-0.28.5\app\exiv2.vcxproj]
LINK : warning LNK4217: symbol 'free' defined in 'libucrt.lib(free.obj)' is imported by 'zlibstat.lib(zutil.obj)' in function 'zcfree' [\exiv2-0.28.5\app\exiv2.vcxproj]
LINK : warning LNK4217: symbol 'malloc' defined in 'libucrt.lib(malloc.obj)' is imported by 'zlibstat.lib(zutil.obj)' in function 'zcalloc' [\exiv2-0.28.5\app\exiv2.vcxproj]

Thank you in advance.

You can download prebuilt binaries from our release page: https://github.com/Exiv2/exiv2/releases/tag/v0.28.5

You can see how we build those binaries here:

Thank you Kevin for your reply. I made a few modifications
to the exiv2 code to suit my project, couldn't use prebuilt binaries and shall take a look
on the build config you gave me. What are the settings for
cmake --preset win-release?

I dig deeper to cmake generation and find that I use
cmake -S . -B build -G "Visual Studio 17 2022" -A x64 -DCMAKE_BUILD_TYPE=Release -DBUILD_SHARED_LIBS=OFF ...
When I switch to
cmake -S . -B build -G "Visual Studio 17 2022" -A x64 -DCMAKE_BUILD_TYPE=Release DBUILD_SHARED_LIBS=ON ...
exiv2 compiles successfully. I also double check that all dependent libraries are compiled with the same
/MD
switch. exiv2.dll is generated!
