Requirements:

Install vcpkg

https://github.com/microsoft/vcpkg#quick-start

git clone https://github.com/Microsoft/vcpkg.git
cd vcpkg

./bootstrap-vcpkg.sh

Install packages

./vcpkg install @vcpkg_response_file.txt

Build:

clone this repo and cd to it

Run cmake wih vcpkg toolchainfile

cmake -Bbuild -DCMAKE_TOOLCHAIN_FILE=$VCPKG_INSTALLATION_ROOT/scripts/buildsystems/vcpkg.cmake

Replace $VCPKG_INSTALLATION_ROOT with the path to your vcpkg repo.

You can also set $VCPKG_INSTALLATION_ROOT as enviroment variable this way you can ommit -DCMAKE_TOOLCHAIN_FILE=

e.g: export VCPKG_INSTALLATION_ROOT=~/Repos/vcpkg && cmake -Bbuild

Excute the build

cmake --build build

Optional: Symmlink compile_commands.json if you use clang based tooling in your IDE/Editor

ln -s build/compile_commands.json .

Run

./build/voxelscape

Recommended editor setup:

• VSCode
• clangd extension for auto completion
• cpp extenstion (with intellisense disabled) for debugging
