Yes, there a breaking change in v1.8.3, unfortunately not communicated well. Starting v1.8.3 (PR #2022), the cmake install rules are not created by default, and need to explicitly specify the CMAKE option OPENTELEMETRY_INSTALL to create them. Please use this option from now. It is still not finalized if default install should be enabled back.
