+Subject: [PATCH] Search for the library containing: tigetnum (tinfo)
+
+For me, `tigetnum` is found in tinfo.so, ncurses has been split off into
+tinfo due to being compiled with the --with-termlib flag.
+
+pkg-config --libs automatically reports this, but this check is good
+enough to catch this specific problem.
