Subject: Allow running gst-uninstalled when GStreamer is a subproject
X-Git-Tag: 1.22.0~2305
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=57158f419491a98585054d9554d8a6c702684bc7;p=platform%2Fupstream%2Fgstreamer.git

Allow running gst-uninstalled when GStreamer is a subproject

As described in Merge request 222, the previous solution is not the
best possible solution and was also missing documentation.
Adjust the suggestion to the current GStreamer mono-repository.
And apply this change after reverting the previous commit.
