Cannot load library libcairo-2.dll

[pdomenighetti]

I proceeded to install Conda and origami; it appears that libcairo-2.dll is not generated because I got the following error (on Windows 10):

Apparently after swimming in the depths of Windows DLLs a simple conda install cairo in conda prompt solved the issue. I'll let this issue and close it for future users that could stumble into it.
