libcamerasrc doesn't exist after buildin from source.

Hi, I installed this version of libcamera like this: meson build --buildtype=release -Dpipelines=rpi/vc4 -Dipas=rpi/vc4 -Dv4l2=true -Dgstreamer=enabled -Dtest=false -Dlc-compliance=disabled -Dcam=disabled -Dqcam=disabled -Ddocumentation=disabled -Dpycamera=enabled

the camera is correctly detected: `ubuntu@ubuntu:~/libcamera$ libcamera-hello --list-cameras Available cameras

0 : ov5647 [2592x1944 10-bit GBRG] (/base/soc/i2c0mux/i2c@1/ov5647@36) Modes: 'SGBRG10_CSI2P' : 640x480 [58.92 fps - (16, 0)/2560x1920 crop] 1296x972 [43.25 fps - (0, 0)/2592x1944 crop] 1920x1080 [30.62 fps - (348, 434)/1928x1080 crop] 2592x1944 [15.63 fps - (0, 0)/2592x1944 crop]`

However gstreamer can't find the libcamerasrc plugin. WARNING: erroneous pipeline: no element "libcamerasrc"

Issue seems to be the path where the plugin is copied. When adding export GST_PLUGIN_PATH=/usr/local/lib/aarch64-linux-gnu/gstreamer-1.0:$GST_PLUGIN_PATH It at least loads.

However the pipeline crashes:

All of this works when installing just the binary on Raspbian.

You haven't given the GStreamer pipeline you're trying to run, and if it contains appsink then there's obviously more than just the pipeline going on. Cut your use case down to the basics for test purposes. You also appear to have ignored the error message

Raspberry Pi OS is the only OS that Raspberry Pi directly support. Support for Ubuntu comes from Canonical.
