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
