[yocto] net-snmp_5.8.bb failed to compile

[Simon Chamlian]

How can I avoid mixing branches.

I already have a meta-openembedded layer, which supports net-snmp_5.7.3
(which compiles but I want to update).

Now I cloned a new meta-openembedded layer, which as net-snmp_5.8.

How can I merge the layers (meta-openembedded that I have and the new
cloned one)?
