+ [WPE] Add env var WPE_USE_HEADLESS_VIEW_BACKEND
+ https://bugs.webkit.org/show_bug.cgi?id=173770
+
+ Reviewed by Michael Catanzaro.
+
+ Move HeadlessViewBackend implementation to a common place and build it as a private static library to be used by
+ WTR, GLib API tests and eventually C API tests too. WTR uses the HeadlessViewBackend unconditionally, but GLib
+ API tests use it only when WPE_USE_HEADLESS_VIEW_BACKEND environment variable is present and not "0".
+
+ * CMakeLists.txt: Include wpe/HeadlessViewBackend directory for developer builds.
