Is this .lib a static library, or an import library of the .dll ? My 
assumption (I may be wrong) is that it is an import lib of the .dll. In 
which case you must not set EXPAT_USE_STATIC_LIBS

That won't work. This needs to be a .lib

You'd better run cmake again on expat with a 
-DCMAKE_INSTALL_PREFIX=d:/install-prefix   and run "cmake --build . 
--target install", and then when building GDAL, use "cmake .. 
-DCMAKE_PREFIX_PATH=d:/install-prefix", so it automatically configures 
things from what is found in d:/install-prefix

You could also potentially use vcpkg or conda to install GDAL 
dependencies instead of building them from scratch:
