Compile fails with dependency on aws-c-auth private headers

• I've gone though Developer Guide and API reference
• I've searched for previous similar issues and didn't find any solution

Describe the bug
Error when compiling.

SDK version number
1.9.95 and later.

Platform/OS/Hardware/Device
Amazon Linux 2. GNU Guix.

To Reproduce (observed behavior)
When building aws-sdk-cpp with "-DBUILD_DEPS=OFF" (having installed the dependent AWS libraries separately) the build fails due to a dependency on the aws-c-auth private libraries which are not installed to the system.

The compile error is:
/tmp/guix-build-aws-sdk-cpp-1.9.121.drv-0/aws-sdk-cpp-1.9.121-checkout/aws-cpp-sdk-core-tests/aws/auth/AWSAuthSignerTest.cpp:17:10: fatal error: aws/auth/private/aws_signing.h: No such file or directory #include <aws/auth/private/aws_signing.h>

The change was made on 2021-06-04 in commit 23cca02.

Expected behavior
Clean build.

Hi @greghogan ,
Can you walk me through how you installed the dependencies separately so I can better reproduce this issue?

Got the same error here. The solution is to get https://github.com/awslabs/aws-c-auth to install the include/aws/auth/private directory, which seems wrong (well, it's called private for a reason I guess...).

Patching aws-c-auth with this will do the tricky, but again, it seems wrong.

I've installed all the aws-sdk-cpp's dependencies separately (-DBUILD_DEPS=OFF).

@daniloegea ,
Hey and thanks for the workaround! I never got an answer from op but could you tell me how you installed the deps ? Like, can you walk me through your process step by step so I can repro and maybe push this as a change if necessary?

Hi @KaibaLopez, I didn't do anything special really.

I simply built all the aws-sdk-cpp dependencies (these ones https://github.com/awslabs/aws-crt-cpp/blob/main/.gitmodules) and installed at /usr/local.

Then I built aws-sdk-cpp with -DBUILD_DEPS=OFF so it will look for dependencies installed in the system. The compilation failed due to the error described above. The solution was to patch aws-c-auth to install the private headers.

It was part of the work to update the aws-sdk-cpp in the FreeBSD ports tree https://cgit.freebsd.org/ports/tree/devel/aws-sdk-cpp/Makefile

I built everything on FreeBSD.
