From 96a0d99c72cc4eb4f1b2acb71580693b91b95b28 Mon Sep 17 00:00:00 2001 From: Brian Norris Date: Tue, 17 Feb 2015 18:18:35 -0800 Subject: tools/thermal: tmon: use pkg-config to determine library dependencies Some distros (e.g., Arch Linux) don't package the tinfo library separately from ncurses, so don't unconditionally include it. Instead, use pkg-config. The $(STATIC) ugliness is to handle the reported build case from commit 6b533269fb25 ("tools/thermal: tmon: fix compilation errors when building statically"), where a developer wants to be able to build with: make LDFLAGS=-static which requires an additional pkg-config flag. Finally, support a lowest common denominator fallback (-lpanel -lncurses) for build systems that don't have pkg-config entries for ncurses.
