                Cairo dependencies for Windows (to use ggplotnim on Windows)
              
          
    A common issue while trying to use https://github.com/Vindaar/ggplotnim on Windows is the fact that it is not easy to satisfy the full list of dll for Cairo.
In an issue (Vindaar/ggplotnim#57) and related gist (https://gist.github.com/Vindaar/6cb4e93baff3e1ab88a7ab7ed1ae5686) one of the best options seems to be to install emacs and add its bin folder to the path.
Using a dll dependency analyzer (https://github.com/lucasg/Dependencies, found through SO: https://stackoverflow.com/questions/7378959/how-to-check-for-dll-dependency), I was able to list all the dlls required, which are the following 17 files (including libcairo-2.dll, total around 9MB).
So another solution instead of installing emacs is to download the dlls (see link to libcairo-deps.rar in comment) and copy them in ~\.nimble\bin.
List of all recursive dependencies for libcairo-2.dll:

libbz2-1.dll


## to make ggplotnim work on WSL ubuntu
sudo apt-get update
sudo apt-get install libpangocairo-1.0-0
sudo apt-get install libblas-dev liblapack-dev
