I. Adding the meta-user layer to your build
=================================================
--- replace with specific instructions for the meta-user layer ---
In order to use this layer, you need to make the build system aware of
it.
Assuming the meta-user layer exists at the top-level of your
yocto build tree, you can add it to the build system by adding the
location of the meta-user layer to bblayers.conf, along with any
other layers needed. e.g.:
BBLAYERS ?= " \
/path/to/yocto/meta \
/path/to/yocto/meta-poky \
/path/to/yocto/meta-yocto-bsp \
/path/to/yocto/meta-meta-user \
"
