go get github.com/projectcypress/cdatools/...
You will also need go-bindata which you can install with
go get -u github.com/jteeuwen/go-bindata/...
Make sure that $GOPATH/bin is in your path and then run make
Or if you are doing active development you can use make debug which will read the contents of the file each time it's accessed so you don't need to keep rerunning make while building templates.
