CI builds fail if cmake version < 2.21.1

[sachinpro]

The CMakeLists file is unable to find the package google_cloud_cpp_bigquery_rest, if the cmake version installed is < 2.21.1. This leads to CI failures on all linux distributions.

Error logs:

-- Build files have been written to: /workspace/cmake-out
make[2]: *** No rule to make target 'google/cloud/odbc/google_cloud_cpp_bigquery_rest', needed by 
  'google/cloud/odbc/CMakeFiles/odbc_client_interface'.  Stop.

This has been verified locally on docker. After the cmake output files are created, the build succeeds when you retry building with same version.
