Subject: [PATCH 3/3] improve cmake build script ,add install target
currently cmake build script does not generate config.h and
gstglconfig.h automatically, it copy pre-defined header to build dir
instead. now you can use CMake to build gst-plugin-gl with Gstreamer
windows version SDK(MSVC based,version 1.2).
note: pre-defined header assumes png and jpeg is presented (packed in
SDK), but CMake does not found png correctly ,you should copy *.h from
include/libpng15 to include .
