描述

Hi, I saw that on https://github.com/google/benchmark?tab=readme-ov-file#usage-with-cmake the Readme indicates that I should link against both benchmark::benchmark and benchmark::benchmark_main when using CMake. What's the difference between the two? Wouldn't it be enough to just link against benchmark::benchmark_main?

Thanks.

研究方向
The issue asks for clarification on the difference between the two CMake targets. The answer likely lies in the CMakeLists.txt file where these targets are defined. The maintainer should explain that benchmark::benchmark main provides a default main() function, while benchmark::benchmark provides the library without main. The documentation should be updated accordingly.
