Setup
This project uses cmake and vcpkg as dependencies manager.
Downloading vcpkg is not necessary since we use the json manifest in combination with git submodules and direnv.
envrc is only needed to add vcpkg submodule to PATH and boostrap its binaries but both can be done by hand with little extra effort.
Steps
- clone repo with submodules
git clone --recurse-submodules https://github.com/anvouk/anv_benchmarks.git - If direnv is installed:
direnv allow . - If direnv is NOT installed:
cd vcpkg && ./bootstrap-vcpkg.sh
Gluing together vcpkg deps and the benchmarks should now be handled by cmake without further steps.
