Compiling java on windows, linking fails

HI！

I'm on windows, compiling the java interface
First I changed client/CMakeLists.txt

    add_custom_command(
            OUTPUT ovpncli_wrap.cxx ovpncli_wrap.h
            COMMENT "Generating ovpncli Python swig files"
            COMMAND ${SWIG_EXECUTABLE} -c++ -java -package net.vpn.ovpn3 -outcurrentdir -I${CORE_DIR} ${CMAKE_CURRENT_SOURCE_DIR}/ovpncli.i
            DEPENDS ovpncli.i
    )

	target_include_directories(ovpnclilib PRIVATE $ENV{JAVA_HOME}/include/)
	target_include_directories(ovpnclilib PRIVATE $ENV{JAVA_HOME}/include/win32/)

then

    > git clone https://github.com/OpenVPN/openvpn3.git core && cd core
    > cmake -B build -S . -DCMAKE_TOOLCHAIN_FILE=<path_to_vcpkg>\scripts\buildsystems\vcpkg.cmake -DVCPKG_OVERLAY_PORTS=deps\vcpkg-ports
    > cmake --build build --config Release --target ovpncli

compile link error

5 ports included

      virtual void connect_attach();
      virtual void connect_pre_run();
      virtual void connect_run();
      virtual void connect_session_stop();
      virtual Stop* get_async_stop();

Start in client/CMakeLists.txt and inspect how ovpncli_wrap.cxx and the ovpnclilib target are generated and linked for the Java interface. Reproduce the shown CMake configure and build commands on Windows, then verify that the Release build completes without the listed unresolved OpenVPNClient symbols.
