+Subject: [PATCH] Fix include gstreamer path on cross compiler toolchains
+ https://bugs.webkit.org/show_bug.cgi?id=241483
+
+Reviewed by Adrian Perez de Castro.
+
+Set the include paths for the gstreamer components to the full path
+using the find_path(). This function relies in CMAKE_FIND_ROOT_PATH to
+find the right place where the includes they are. This fixes possible
+warnings/errors on cross toolchains using -Wpoison-system-directories
+and -Werror=poison-system-directories.
