Hi @mnistor1 ,
Could you explain a bit on how you came across this error? From the description it sounds like you just built for debug and got it but that's not reproducible on my side so I'm wondering what else is happening for you to get this error.
Can you walk me through what steps you took to build (or maybe link?) the sdk ?

Hello @KaibaLopez,

You can reproduce it very easily if you set the CMAKE_DEBUG_POSTFIX when you build the aws sdk.

The commands are below:
cd <BUILD_DIR>
cmake -DCMAKE_BUILD_TYPE=Debug -DCMAKE_DEBUG_POSTFIX=”-d” -DCMAKE_PREFIX_PATH=
make
make install

You can noticed that all libraries have the included -d in the name of library.

The error appears when you want to use one of aws sdk libraries by using find_package. E.G. find_package(AWSSDK REQUIRED COMPONENTS core)

BTW: A similar problem can appear it you set CMAKE_RELEASE_POSTFIX, CMAKE_RELWITHDEBINFO_POSTFIX or CMAKE_MINSIZEREL_POSTFIX

You can see the patch that solves the problem.

Greetings! Sorry to say but this is a very old issue that is probably not getting as much attention as it deservers. We encourage you to check if this is still an issue in the latest release and if you find that this is still a problem, please feel free to open a new one.
