bah, there used to be precompiled x64 files for windows so one cpuld 
just drop in the dll (kind of strange to stick to 32 bit as most windows 
installations today are 64 bit)

although i don't like top do it i cloned the zint repos and tried to 
compile (after migrating the proj file to vs2022) but it fails on some 
png.h file missing and i see no way to disable png)

a pitty as zint used to be quite stable over years (at some point we 
will set up compilation on the farm and then we can stick to old stable 
versions forever)

anyway, so instead of trying that i went for a quick and dirty cross 
compile on wls

# mingw-64.cmake

set(CMAKE_SYSTEM_NAME Windows)
set(TOOLCHAIN_PREFIX  x86_64-w64-mingw32)
set(CMAKE_C_COMPILER  ${TOOLCHAIN_PREFIX}-gcc)

and on build then run

mkdir build
cd build
cmake -DCMAKE_TOOLCHAIN_FILE=../mingw-64.cmake ..
make

which gives me a huge dll that we can strip to some 600+K and that one 
seems to load ok

it assume of course that you have the linus subsystem installwd with gcc 
and the crosscompiler (which i have as it is how i compile luametatex)
