Hi,
I am trying to compile my code using yocto. For that I have created two
layers: "meta-networking" and "meta-oe". I have added these dependencies in
bblayer.conf too. But these are not getting build. Can anyone please tell
me what should I do to make this work.

More details are needed to be able to help.
What do you mean "not getting built"? Do you mean that if you
try to build recipe XYZ which is in one of those layers that it's
not being built? Or perhaps you mean something else?
What do you mean "created two layers: ..."? Did you just extract
these from meta-openembedded? or something else?

Actually the package which I am building is having some dependencies on
some libraries. So I provided those libraries with the help of creating
layers. I did not extract those from meta-openembedded, instead, I manually
created two layers and added them in bblayer.conf file. Now, after
configuring all this stuff I am again trying to recompile my code but still
I am getting the same error saying that it is not able to find those
libraries provided by me in the form of layers.

Can you please paste your command and it's output here..! If you don't
mind..!! Or explain with equivalent clarity. It
l will good if you can also put in your directory structure.

I am building one of my application using yocto by giving bitbake -k
core-image-minimal command but I am facing some errors as this application
requires two libraries
*1) net-snmp*
*2) fuse*
*
*
I have one link where in they are asking to add these two libraries in the
form of layers and then execute bitbake -k core-image-minimal command.
I am pasting one screenshot below:
As you can I have added two layers meta-networking (contains net-snmp) and
meta-oe(contains fuse). After this I added these layers in *
build/conf/bblayer.conf.*
*
*
*
*
After this I again executed bitbake -k core-image-minimal command but I
faced the same error as before... :(
Is there anyway that these layers get recognized? Do I need to execute some
other command?

Obviously, this is a recipe that you made.
Does it show these dependencies? e.g. a line like this in your recipe file:
DEPENDS = "net-snmp fuse"
(or whatever the *packages* that you need are)
Bitbake can't read your mind; it will only build the recipes you ask and the
dependencies which are explicitly specified in that build chain.
If you still have trouble, try sending your recipe (.bb file and all other
components you might have), bblayers.conf, etc to the list because we're not
mind readers either :-)

Thanks for the reply Gary. I am attaching recipe file below. Please have a
look at it. And yes, there is a line where in all the dependencies are
given.
And this is the link from where I created the layer :
