## Motivation - Structured logging with proper log levels (TRACE, DEBUG, INFO, WARNING, ERROR, CRITICAL) - Better performance through compile-time formatting - Consistent formatting using fmt library - Runtime log level control via arguments and environment variables - Easier maintenance and debugging capabilities ## Technical Details - Added spdlog as a submodule and integrated it into CMake build system - Created new `rocprofiler-systems-logger` library wrapping spdlog functionality - Replaced custom logging macros (`ROCPROFSYS_VERBOSE`, `ROCPROFSYS_DEBUG`, `ROCPROFSYS_FATAL`, `ROCPROFSYS_REQUIRE`, `ROCPROFSYS_CI_THROW`, etc.) with spdlog equivalents (`LOG_DEBUG`, `LOG_WARNING`, `LOG_CRITICAL`, etc.) - Implemented log level control through command-line arguments and environment variables - Converted assertion macros to proper error handling with exceptions and std::abort()
