Are you referring to Cygwin packages when you say "libraries"? The Cygwin downloader we offer on <http://www.webkit.org/building/tools.html> is supposed to install all required Cygwin packages. If there are packages missing, please file a bug at http://webkit.org/new-bug and CC me so we can fix it.

This is <https://bugs.webkit.org/show_bug.cgi?id=34804>.

Maybe Brent can comment on why this is required.

Do you have CFLite installed somewhere where the build can find it?
