JOHNE - Create (i.e. ensure the existence of) any folders that we'll need at build time
JOHNE - A newer version of freetype has simplified the folder structure for #include files. Instead of being in '<include_folder>/freetype2/freetype' they're now directly in '<include_folder>/freetype'. To accommodate the change, this (older) freetype will need to copy its header files to both sets of folders. Otherwise, new versions of cairo, pango, harfbuzz etc would be stuck indefinitely with this older version of freetype.
