project uses cmake and [vcpkg](https://vcpkg.io/en/) as dependencies manager.\n\nDownloading vcpkg is not necessary since we use the json manifest in combination\nwith git submodules and [direnv](https://direnv.net/).\n\nenvrc is only needed to add vcpkg submodule to PATH and boostrap its binaries but both\ncan be done by hand with little extra effort.\n\n### Steps\n\n1. clone repo with submodules `git clone --recurse-submodules https://github.com/anvouk/anv_benchmarks.git`\n2. If direnv is installed: `direnv allow .`\n3. If direnv is NOT installed: `cd vcpkg \u0026\u0026 ./bootstrap-vcpkg.sh`\n\nGluing together vcpkg deps and the benchmarks should now be handled by cmake\nwithout further steps.\n\n## License\n\nAll tested libraries are under their respective licenses (see include headers).\n\nRemaining code is under MIT License.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fanvouk%2Fanv_benchmarks","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fanvouk%2Fanv_benchmarks","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fanvouk%2Fanv_benchmarks/lists"}
