Welcome

Yes, in principle, it's possible to add OPTION_USE_CAIROPS as a new build (or configure) option.

BTW: my point was not to add a new option but to fall back sensibly if Cairo is not available. But that's now moot, see below.

But my feeling, at this point, is that this would not correspond to real-life situations because:

- OPTION_USE_PANGO requires package libpango-1.0-dev to get both libpango-1.0.so and pango-related include files. In Debian and Ubuntu, that package includes libpangocairo-1.0.so . Thus, when OPTION_USE_PANGO's requirements are satisfied, libpangocairo-1.0.so is also there,
at least with Debian/Ubuntu.

Yep, thanks for that info. I verified that (on my Linux Mint - based on Ubuntu) libpango1.0-dev explicitly depends on libcairo2-dev and libpangocairo-1.0-0 which removes my concerns. Hence...

+1 on this awesome improvement

and many thanks for your continuing great work on such additions!

P.S. I found okular, and its "Import PS file" command, useful to display .ps files under Debian.

As Ian wrote I never had problems viewing .ps files on Linux. Mint comes with `xreader' which opens .ps and .pdf files and, as Ian wrote, `evince' which is now a symbolic link to `xreader':

$ file /usr/bin/evince
/usr/bin/evince: symbolic link to /usr/bin/xreader
