[libcamera-devel] [PATCH] gstreamer: Add meson devenv support

[Nicolas Dufresne]

From: Nicolas Dufresne <nicolas.dufresne at collabora.com>

This change to the build system will prepend the plugin build directory
to GST_PLUGIN_PATH environment. This makes the built plugin visible to
GStreamer inside meson devenv enabling uninstalled testing.
