how does one build this?

1. seems to have a circular dependency with cstor...
2. the configure options --with-spl-headers and --with-zfs-headers seem to require absolute paths and automatically prepend a -I to the supplied paths instead of prepending it for the includes.

Description

I got some strange errors about the libjson library. Apologies if this is in the wrong repository.

❯ k logs cstor-sparse-pool-w39i-65b4d88bbf-f4mzd cstor-pool
Disabling dumping core
sleeping for 2 sec
/usr/local/bin/zrepl: error while loading shared libraries: libjson-c.so.2: cannot open shared object file: No such file or directory

Environment:

• OpenEBS version: 1.9.0 (Also tried using 1.10.x.RC2)
• Kubernetes version: 1.18.x
• OS: Ubuntu 20.04 Focal
• Hardware: Raspberry Pi 4B

What steps did you take and what happened:
Travis fails intermittently. It is hard to debug the cause for the failure by looking at the logs. Restarting on the build usually passes the build.

What did you expect to happen:
The cause for build failure in travis should be easy to debug.

The output of the following commands and cstor pod logs will help us better understand what's going on:
The logs from one of the failures are as follows:
