Sorry, I don't have native windows compiler to test, but the options you
probably want with zint's cmake are:

    -DZINT_USE_PNG=OFF -DZINT_USE_QT=OFF

For example I use:

    cmake -S . -B build -DCMAKE_BUILD_TYPE=Release -DZINT_USE_PNG=OFF -DZINT_USE_QT=OFF

from the root of repository. IIRC older versions may not support
-S for source directory and -B for build directory so something like you
had can be used:


    mkdir build
    cd build
    cmake -DZINT_USE_PNG=OFF -DZINT_USE_QT=OFF ..

The ZINT_USE_PNG cmake option decides whether to pass -DNO_PNG to the
compiler. In my repository I don't use zint's cmake at all, and compile
the files manually (though also with cmake), and I set NO_PNG
unconditionally:

For older versions following should work:


    -DCMAKE_TOOLCHAIN_FILE=cross-windows.cmake

instead of the newer:

    --toolchain cross-windows.cmake
