## Setup
This project uses cmake and [vcpkg](https://vcpkg.io/en/) as dependencies manager.
Downloading vcpkg is not necessary since we use the json manifest in combination
with git submodules and [direnv](https://direnv.net/).
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
1. clone repo with submodules `git clone --recurse-submodules https://github.com/anvouk/anv_benchmarks.git`
2. If direnv is installed: `direnv allow .`
3. 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.
