From 694f1f926c725a8955c1c156ad6d3c4e1b853bd8 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Daniel=20D=C3=ADaz?= Date: Tue, 16 Oct 2018 16:46:59 -0500 Subject: [PATCH] selftests: gpio: Find libmount with pkg-config if available MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit If pkg-config is available, use it to define the CFLAGS and LDLIBS needed for libmount; else, use the current hard-coded paths and options. Using pkg-config is very helpful for cross-compilation environments, and is sometimes readily available on developer boxes to ensure we get the right compiler/linker options for the given package.
