(short issue description)Cannot build on Ubuntu 25.10

[shekarman1]

Describe the bug

Not sure what the issue is but I followed instructions to build and install aws-sdk-cpp -- tried on master branch and release/1.9 but getting the same issue.

~/aws-sdk-cpp/build $ cmake .. -DCMAKE_BUILD_TYPE=Release -DBUILD_ONLY="core;firehose" -DCMAKE_PREFIX_PATH=/usr/local -DCMAKE_INSTALL_PREFIX=/usr/local

`Make Deprecation Warning at CMakeLists.txt:5 (cmake_minimum_required):
Compatibility with CMake < 3.10 will be removed from a future version of
CMake.

Update the VERSION argument value. Or, use the ... syntax
to tell CMake that the project requires at least but has been updated
to work with policies introduced by or earlier.

CMake Deprecation Warning at CMakeLists.txt:13 (cmake_policy):
The OLD behavior for policy CMP0077 will be removed from a future version
of CMake.

The cmake-policies(7) manual explains that the OLD behaviors of all
policies are deprecated and that a policy should be set to OLD only under
specific short-term circumstances. Projects should be ported to the NEW
behavior and not rely on setting a policy to OLD.

• The path was deleted, renamed, or moved to another location.

• An install or uninstall procedure did not complete successfully.

• The installation package was faulty and references files it does not
  provide.
