Gstreamer boilerplate code is not compiling

Question

I am trying to build Gstreamer custom plugin. I am referring this link.

I followed the instructions given in the website, here are my steps,

1. Cloned the git repo using git clone https://gitlab.freedesktop.org/gstreamer/gst-template.git
2. Created the boiler plate code using below commands

   $ cd gst-template/gst-plugin/src
   $ ../tools/make_element MyFilter
   

3. I verified that, there are gstmyfilter.c and gstmyfilter.h files in the /gst-plugin/src directory.

After this step I am facing issue as Gstreamer documentation is not very clear about this. Documentation says, "run meson build from the parent directory to bootstrap the build environment".

I ran mason build from topmost directory (where we have build, gst-app, gst-plugin folders and mason.build file) But, I am getting below error.

Looking for a fallback subproject for the dependency gstreamer-1.0

meson.build:11:0: ERROR: Subproject directory not found and gstreamer.wrap file not found

A full log can be found at /home/user6/Documents/gstream_examples/custom_gstreamer_plugin/gst-template/build/meson-logs/meson-log.txt

Is it that, I need to upgrade Gstreamer to 1.19?

And does anyone have better guidelines to build the custom plugin? Gstreamer documentation is so good, except this part!!
