============
To compile this software you need to install development packages for
-llvm (version 2.8 or >= 3.0), opengl, curl, zlib, libavcodec, libavresample
+opengl, curl, zlib, libavcodec, libavresample
libglew, pcre, librtmp, cairo, libboost-filesystem,
sdl2, sdl2_mixer, libjpeg, libavformat, pango, liblzma
+If jit compilation using llvm is enabled(disabled by default),
+you also need the development packages for llvm (version 2.8 or >= 3.0)
+
If compiling the PPAPI (Chromium) plugin is enabled (on by default), keep in mind that
it will replace the adobe flash plugin, as only one flash plugin is allowed in chromium.
