Deploy CMake modules as a CMake package

[adamlm]

Summary

The current deployment strategy for the CMake modules in cmake directory (from my understanding) is to copy them to /opt/carma then have consuming packages manually extend CMAKE_MODULE_PATH.

A more streamlined approach would be to deploy them as a CMake package than consuming packages can integrate with the find_package(...) functionality.

Reasoning for new functionality

This would reduce friction for consuming packages that want to use the carma-build CMake modules.
