In the light of the different mails on the subject, it appears that the
ncurses*-config script are unreliable: at least one major distribution
(Debian) is broken and, for various reasons, is not gonna fix it, and
all its derivatives (eg. Ubuntu) do suffer from the same deficiency.
I think we should stick to:
- try with pkg-config;
- fallback to the legacy heuristic.
Does using pkg-config fix your use-case?
