+# Building the AWS SDK for C++
+The driver supports AWS IAM and AWS Secrets Manager authentication by using [AWS SDK for C++](https://docs.aws.amazon.com/sdk-for-cpp/). The driver requires `aws-cpp-sdk-core`, `aws-cpp-sdk-rds`, and `aws-cpp-sdk-secretsmanager`. You can either build the SDK yourself directly from the source using the script under `scripts` folder or [download the libraries using a package manager](https://docs.aws.amazon.com/sdk-for-cpp/v1/developer-guide/sdk-from-pm.html). The script will install the SDK under `aws_sdk/install` folder. The driver will look for SDK dependencies through `aws_sdk/install` folder and `CMAKE_PREFIX_PATH` environment variable.
+> **_NOTE:_** On Winodws, depending on the use case, you may build the SDK as a static library or dynamic library. On Linux and macOS, you should always build the SDK as a dynamic library.
+
+## Windows
+If you want to build and run the driver unit tests, you need to build the SDK as static library, as the unit test binary will link every dependency statically.
+```
+.\scripts\build_aws_sdk_win.ps1 x64 Debug OFF "Visual Studio 16 2019"
+```
+If you want to build the driver DLL, you need to build the SDK as dynamic library, as the driver DLL will link the SDK dynamically.
+```
+.\scripts\build_aws_sdk_win.ps1 x64 Release ON "Visual Studio 16 2019"
+```
+## Linux/macOS
+```
+./scripts/build_aws_sdk_unix.sh Release
+```
+
+## Troubleshoot
+See https://docs.aws.amazon.com/sdk-for-cpp/v1/developer-guide/troubleshooting-cmake.html
