Aws-sdk-cpp: Compiling for Android failing with CMake 3.10.2

[naja1987]

What platform/OS are you using?

Ubuntu 18.04.2

What compiler are you using? what version?

CMake 3.10.2

What's your CMake arguments?

cmake -DBUILD_ONLY="s3;iot" -DENABLE_TESTING=OFF -DTARGET_ARCH=ANDROID -DNDK_DIR=/path/to/android-ndk-r12b ..

Can you provide a TRACE level log? (sanitize any sensitive information)

Interestingly, with CMake version 3.6 it is working (I used the one provided by Android Studio).

Thank you for reporting this issue.
We are using a quite old NDK, which is not compatible with the new cmake.
And we are trying to make SDK build with latest Android NDK right now.

Now we support latest NDK r19c (back to 13b) with their own toolchain files, 12b is not supported anymore. Please reopen if you still have problem.
