As stated in the [installation guide], the easiest way to get up and running
with the [Cairo Graphics] library on Windows is by installing [GTK+]. You
can also download a precompiled [GTK runtime].
The easiest way to get up and running with the [Cairo Graphics] library is
by installing it via [MSYS2], which is a software distribution and building
