Initial import from the monolithic Qt. This is the beginning of revision history for this module. If you want to look at revision history older than this, please refer to the Qt Git wiki for how to use Git history grafting. At the time of writing, this wiki is located here: http://qt.gitorious.org/qt/pages/GitIntroductionWithQt If you have already performed the grafting and you don't see any history beyond this commit, try running "git log" with the "--follow" argument. Branched from the monolithic repo, Qt master branch, at commit 896db169ea224deb96c59ce8af800d019de63f12 2011-04-27 10:05:43 +00:00			`SOURCES = libpng.cpp`

Libpng config.tests: use pkg-config when available Add pkg-config to the libpng usages as not all systems have the symlink libpng.so -> libpng<version>.so (affected: NetBSD) that changes with the version of the lib. If no-pkg-config is used, use -lpng as before. Tested with FreeBSD 10.3, NetBSD 7.0.1 using png 1.6.21 Change-Id: I5c87f380c84da3d5c56c94da53adb900791c8caa Reviewed-by: Oswald Buddenhagen <oswald.buddenhagen@theqtcompany.com> 2016-06-24 20:33:31 +00:00			`!contains(QT_CONFIG, no-pkg-config) {`
