Resolve cmake dependencies (AWS::crypto)

[abhisen7]

Hello, I am trying to link my project against aws-cpp-sdk-*, specifically for S3 client operations. This is how a relevant part of project CMakeLists.txt look like:

add_dependencies(packfuzzer radamsa_build)

find_package(AWSSDK REQUIRED COMPONENTS s3 core)

# Link radamsa, curl, and AWS SDK libs 
target_link_libraries(packfuzzer PRIVATE
    radamsa
    curl
    ${AWSSDK_LINK_LIBRARIES}
  

Steps I followed to build and install the aws-cpp-sdk-* for s3:

$ cmake ../contrib/aws -DBUILD_ONLY="s3" -DCMAKE_POLICY_VERSION_MINIMUM=3.5 -DENABLE_TESTING=OFF -DENABLE_OPENSSL_ENCRYPTION=ON

$ cmake --build . --config=Debug

$ sudo cmake --install . --config=Debug

Post successful installation, I can see all the libs:

$ ls -l /usr/local/lib/

But when I run cmake for compiling my project, I get an AWS::crypto dependency error. How can I fix this?

CMake Error at /usr/local/lib/s2n/cmake/static/s2n-targets.cmake:62 (set_target_properties):
 The link interface of target "AWS::s2n" contains:

   AWS::crypto

 but the target was not found.  Possible reasons include:

   * There is a typo in the target name.
   * A find_package call is missing for an IMPORTED target.
   * An ALIAS target is missing.

why are you setting ENABLE_OPENSSL_ENCRYPTION=ON? if you do not know the answer, removing that will likely fix your problem. otherwise what is the reason for explicitly setting that?
