Can you tell me your system specs, i.e. what distro is this? I will try to reproduce it in the meantime.

Sure. I am using CentOS 7. Related tool version: cmake - 3.14.4 Python - 3.7.1 gcc -8.2

Let me know if you need more information. Thanks !

The issue was with way python was configured and installed. I re-installed python and configured with --enable_shared switch. Now, it is working.
