Fix cairo1 & cairo2 builds in Makefile

[fmoletta]

In order to install versions 1 & 2 of the cairo compiler for both macos and not macos systems, a rule was used to check weather the directory existed and build it. As two different behaviours where expected when building for macos and not for macos, two rules were added, one for the cairoX directory and one for cairoX-macos directory, but both of them built the cairoX directory. This lead to makefile erros when building for macos, as the rule would check for the cairoX-macos directory which didn't exist and then fail when the cairoX directory did exist.
This PR uses conditionals to check weather the directory cairoX exists, solving this issue.
Closes #1389
Also contains fix from #1388
