Please, read my previous email. GStreamer do not provide cmake specific
package. If one exist, it is most likely out-dated. Use PkgConfig
package finder with the rather complete instruction I have provided.

GStreamer implement standard pkg-config metadata. CMake provides the
PkgConfig package to let you interface with that. Here's an exemple:

find_package(PkgConfig)

pkg_check_modules(GST REQUIRED gstreamer-1.0>=1.4
                               gstreamer-sdp-1.0>=1.4
                               gstreamer-video-1.0>=1.4
                               gstreamer-app-1.0>=1.4)

Notice that GStreamer is a collection of libraries. The list will
depend on your application needs. From there you'll have to update few
things. Globally, link_directories with ${GST_LIBRARY_DIRS} (only
needed if you use GStreamer from non-system installation). And per
target:
 - target_include_directories with ${GST_INCLUDE_DIRS}
 - target_compile_options with ${GST_CFLAGS}
 - target_link_libraries with ${GST_LIBRARIES}

You'll also have to choose between private and public exposure
depending if you create an app or library and if you expose GStreamer
through your library or not.
