Well, it is how Gtk is (and most other C libraries are as well).

In fact the advise is correct. You should install MSYS2 and then *from* 
MSYS2 you do Cairo developing packages. The package management tool 
under MSYS2 is pacman.

Alternatively you can use MinGW packages from Debian or Fedora if you 
are more comfortable with apt and dnf/yum than with MSYS2 pacman.

Even simpler would be to install GtkAda. That includes Cairo. It is 
really simple: download, execute, ready.

There is a reason why we dislike C. It is not much for the language as 
for the damage it inflicts on software developers, for the "culture of C".
