Subject: build: Add --with(out)-cairo configure option
X-Git-Tag: 1.35.0~5
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=fe8d5ce6975bda30839413f71ab3e192a582300b;p=platform%2Fupstream%2Fpango.git

build: Add --with(out)-cairo configure option

Some builders (e.g. GNOME and jhbuild) hard depend on pangocairo,
and we really don't want to emit a build of pango without support
for it.  So jhbuild can specify --with-cairo, and we'll get
a hard error.
