From 0dfb289a3b362b082ac3608d887e42f09dadc0d2 Mon Sep 17 00:00:00 2001 From: Thomas Petazzoni Date: Mon, 31 Dec 2018 16:22:07 +0100 Subject: [PATCH] Properly detect the availability of pthread_setname_np() This commit adds a CMake check for the availability of pthread_setname_np(), and only uses it on Linux when available. Indeed, some C libraries, such as uClibc, do not provide this non-POSIX function in all cases.
