Subject: use pkg-config for ncurses by default
X-Git-Tag: v3.3.3~69^2
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=96e86ef1a0c9288711329761eccfb279fcd90790;p=procps-ng

use pkg-config for ncurses by default

Newer ncurses install pkg-config files, so search those first.  If they
aren't found, fall back to existing detection logic.
