The library is available on GitHub :
Once inside your project folder, simply run the following command to clone the library's code repository :
git clone https://github.com/Foalyy/libtungsten.git
You can then copy the templates if you want to start from there :
cp libtungsten/template/Makefile.template Makefile
cp libtungsten/template/myproject.cpp.template myproject.cpp
More information in the Getting started tutorial.
If you don't have git, you can also directly download the ZIP of the latest version here : https://github.com/Foalyy/libtungsten/archive/master.zip
