fatal error: openssl/bio.h: No such file or directory in Yocto

Question

My Yocto sources are on Warrior currently and I am in a process of migrating them to dunfell so I cloned all the required layers for dunfell branch including meta-swupdate.

Now, I am trying to generate swupdate image by bitbake swupdate-image command for dunfell and I am getting errors as given below:

Looks like it is unable to find ssl related header files. Any lead on this?

There is no openssl dependency in the swupdate recipe.

Adding DEPENDS += "openssl" in a swupdate_%.bbappend file helps.
