Unresolved External Symbols when Using Static Libraries

[jasonabuzzell]

(Making a separate thread for this issue since it was unrelated to my previous open bug.)

I'm currently trying to use the AWS SDK for C++ to invoke a Lambda function (using Visual Studio 2022). I'm testing using the standard sample code below:

#define USE_IMPORT_EXPORT
#define USE_WINDOWS_DLL_SEMANTICS

#include <aws/core/Aws.h>
int main(int argc, char** argv)
{
    Aws::SDKOptions options;
    Aws::InitAPI(options);
    {
        // make your SDK calls here.
    }
    Aws::ShutdownAPI(options);
    return 0;
}

To get the static libraries needed for this, I did the following steps:

1. Get CMake 3.21.7 and add to PATH
2. C:\Users\Jason > git clone --recurse-submodules https://github.com/aws/aws-sdk-cpp
3. 2.5 C:\Users\Jason > git submodule update --init --recursive
4. C:\Users\Jason > mkdir sdk_build
5. C:\Users\Jason > cd sdk_build
6. C:\Users\Jason\sdk_build > cmake "..\aws-sdk-cpp" -DCMAKE_BUILD_TYPE=Release -DCMAKE_PREFIX_PATH="C:/Program Files (x86)/aws-cpp-sdk-all" DFORCE_SHARED_CRT=OFF -DBUILD_SHARED_LIBS=OFF
7. C:\Users\Jason\sdk_build > cmake --build . --config=Release
8. C:\Users\Jason\sdk_build > cmake --install . --config=Release
9. In Visual Studio, add "C:\Program Files (x86)\aws-cpp-sdk-all\include" to Release Configuration: Additional Include Directories
10. In Visual Studio, add "aws-cpp-sdk-core.lib;aws-cpp-sdk-s3.lib;aws-c-auth.lib;aws-c-cal.lib;aws-c-common.lib;aws-c-compression.lib;aws-c-event-stream.lib;aws-checksums.lib;aws-c-http.lib;aws-c-io.lib;aws-c-mqtt.lib;aws-crt-cpp.lib;aws-c-s3.lib;aws-c-sdkutils.lib;aws-cpp-sdk-lambda.lib;%(AdditionalDependencies)" to Release Configuration: Additional Dependencies
11. Add the project folder under Release Configuration: Additional Library Directories to get static libraries.
12. Copy above libs and corresponding dependencies and add them to the project folder (next to main.cpp)
13. Build and run in Release mode.

The errors that I get are both external symbol errors:

• main.obj : error LNK2001: unresolved external symbol "__declspec(dllimport) void __cdecl Aws::ShutdownAPI(struct Aws::SDKOptions const &)" (_imp?ShutdownAPI@Aws@@YAXAEBUSDKOptions@1@@z)
• main.obj : error LNK2001: unresolved external symbol "__declspec(dllimport) void __cdecl Aws::InitAPI(struct Aws::SDKOptions const &)" (_imp?InitAPI@Aws@@YAXAEBUSDKOptions@1@@z)

Unsure what I'm missing here, but I'm guessing I need to fill another field with where the static libraries are. Thank you for the help!
