benchmark

Uses a simple BENCHMARK macro similar to unit testing frameworks, making it easy to define and register benchmark functions, as shown in the basic usage example with BM_StringCreation.

Provides comprehensive metrics like mean, median, and standard deviation, helping analyze performance variability accurately, as highlighted in the features list.

Offers CMake targets like benchmark::benchmark for easy linking via find_package or add_subdirectory, simplifying project setup as described in the usage section.

Supports parameterized benchmarks and multithreaded code, allowing performance testing across different inputs and concurrency levels, per the key features.
