I'm struggling to install git-subtree with Cygwin and there hasn't been any good tutorials online focused on building from source in Windows. Have you ever had this issue, and what is the best strategy to tackle it?

git-subtree is not part of a package. However, like gitk you can manually
install it
wget rawgit.com/git/git/master/contrib/subtree/git-subtree.sh install git-subtree.sh /bin/git-subtree
