Linker errors with ai::ArtboardList and ai::ArtboardProperties - C++ Plugin SDK2025

Hi All, I am writing a simple C++ plugin to display the number of art boards and their names using latest 2025 SDK. I have taken the EmptyPanel project from SDK samplecode and added below code for displaying artboard info.

AIDocumentHandle doc;
ASErr error = sAIDocument->GetDocument(&doc);
if (error)
{
  sAIUser->MessageAlert(ai::UnicodeString("No active document found."));
  return error;
}

ai::ArtboardID artboardCount = 0;
ai::ArtboardList artboardList;
sAIArtboard->GetArtboardList(artboardList);
sAIArtboard->GetCount(artboardList, artboardCount);
ai::UnicodeString artBoardInfo = ai::UnicodeString("Total Artboards: ") + ai::UnicodeString(std::to_string(artboardCount)) + ai::UnicodeString("\n");
ai::ArtboardProperties requiredArtBoardProperties;
for (ai::int32 i = 0; i < artboardCount; ++i)
{
   ai::ArtboardProperties properties;
   if (sAIArtboard->GetArtboardProperties(artboardList, i, properties) == kNoErr)
   {
      ai::UnicodeString name;
      properties.GetName(name);
      artBoardInfo += ai::UnicodeString("Artboard ") + ai::UnicodeString(std::to_string(i)) + ai::UnicodeString(": ") + name + ai::UnicodeString("\n");
   }
}
sAIUser->MessageAlert(artBoardInfo);
//sAIUser->MessageAlert(ai::UnicodeString("This is a Dialog"));
handled = true;

I have added code to acquire the required suites but getting linker errors for ai::ArtboardList and ai::ArtboardProperties. My development setup details are  

• Illustrator version: v29.7 (64-bit) - 2025

• SDK version: Adobe_2025_SDK

• Operating system: Windows 10 64-bit

• IDE: Visual Studio 2022

The linker errors are :

Any suggestions for resolving these linker errors? Thanks in advance!
