Describe the bug

When compiling a project that uses the SDK as a dependency and resolves said dependency with pkgconfig, the AWS SDK ends up injecting -std=c++11 into the compilation flags of the main project. This appears hard-coded in the configuration:

Regression Issue

• Select this option if this issue appears to be a regression.

Expected Behavior

The dependency should not inject any c++ standard requirements into the parent project

Current Behavior

Compilation fails for projects newer than C++11

Reproduction Steps

Create a module that uses a C++14 feature, like so:

auto doNothing() {
}

int main() {
  return 0;
}

Attempting to compile this with a dependency on aws-cpp-sdk-core will fail:

$ gcc `pkg-config --cflags aws-cpp-sdk-core` main.cc
main.cc:1:1: error: ‘doNothing’ function uses ‘auto’ type specifier without trailing return type
    1 | auto doNothing() {
      | ^~~~
main.cc:1:1: note: deduced return type only available with ‘-std=c++14’ or ‘-std=gnu++14’
