There are hundreds of meta layers from the Yocto Project, OpenEmbedded, communities, and companies that should be manually cloned inside the project source directory to be used. We can find them at http://git.yoctoproject.org/ or http://layers.openembedded.org.
In order to include, for example, meta-openembedded in our project, we can change the content of the configuration files or use BitBake command lines. To do so, we need first to fetch the layer's source code. Please run the following command from your Poky source directory:
$ git clone git://git.openembedded.org/meta-openembedded -b rocko
We can now add a new layer by changing the build/conf/bblayer.conf file and adding the absolute path to the new meta layer directory, as shown in the following source code. The highlighted line is the one to be added. The others are the default values for this file...
