Yes, for a program, I forgot: you need to add -linkpkg (otherwise the
package is only used to compile, not to link).

I would not.  Doing so only allows to write “x” instead of “Cairo.x”.
(You do not need to declare a module in OCaml befor eusing it.)
“Cairo” is not that long, so the latter is fine and makes it clearer
what the origin of the function “x” is.  If it is too long for you,
use “module C = Cairo”.  Then you can write “C.x”.

No, you need to write “Cairo.get_target”.

Best,
