error LNK2001: unresolved external symbol v8::platform::NewDefaultPlatform

I'm getting linking error while trying to create std::unique_ptr<v8::Platform> platform = v8::platform::NewDefaultPlatform(0, v8::platform::IdleTaskSupport::kEnabled); in v8 ver 8.2.77

This my v8 build command

call gn gen out.gn/library --args="is_debug=false is_component_build=true v8_use_external_startup_data=true v8_static_library=false use_custom_libcxx=false use_custom_libcxx_for_host=true v8_enable_i18n_support=false target_cpu=\"x64\""
call ninja -C out.gn/library v8.dll

Link lib(s)

v8.dll.lib
v8_libbase.dll.lib
v8_libplatform.dll.lib

Error Message by Visual Studio 2019
