             Summary: [Build] C++ link is failing Github Actions
                 Key: AVRO-3070
                 URL: https://issues.apache.org/jira/browse/AVRO-3070
             Project: Apache Avro
          Issue Type: Task
            Reporter: Ryan Skraba


It looks like the *{{./build.sh}}* lint command is failing on github actions:

There haven't been any changes to this file, but I noticed that the github C 
compiler versions have bumped from 
[7.5.0|https://github.com/apache/avro/runs/2019837703?check_suite_focus=true] 
to 
[9.3.0|https://github.com/apache/avro/runs/2040426774?check_suite_focus=true].

{code}
Run ./build.sh lint
CMake Deprecation Warning at CMakeLists.txt:19 (cmake_minimum_required):
  Compatibility with CMake < 2.8.12 will be removed from a future version of
  CMake.

  Update the VERSION argument <min> value or use a ...<max> suffix to tell
  CMake that the project does not need compatibility with older versions.
