We want to modify the recipe for the meta-mchp-sasha layer to include two graphics libraries that we want to give to customers as prebuilt binaries, but we do not want to include source code. In our case, we want to include vgraphics.ko and libVgraphics.so in the file system image. Our problem is that we don’t know how to do this, but it seems like a simple set of two recipes and including them using IMAGE_INSTALL += “vgraphics libvgraphics”.

so in your recipe (your-bins.bb) you would provide a SRC_URI which probably is a tar ball containing your binary artifacts. then in you recipe you would have
a do_install () which will take them from WORKDIR and install them wherever they need to be in ${D}${libdir} and so on.

Then you would add a new recipe for your own image say core-image-minimal-custom.bb
which has 

require path/to/core-image-minimal.bb

IMAGE_INSTALL += "your-bins"
