Currently, libpng supports three different types of build automation: the GNU autotools, CMake, and a legacy of hand-made makefiles. In order to simplify the continous integration of all of the above build options, we introduce the following scripts: * ci_autotools.sh: CI utility for the Autotools build * ci_cmake.sh: CI utility for the CMake build * ci_legacy.sh: CI utility for the legacy makefiles
