Found these:
libboost-program-options-dev - program options library for C++ (default 
version)
libboost-program-options1.74-dev - program options library for C++
libboost-program-options1.74.0 - program options library for C++

So did:
sudo apt -y install libboost-program-options-dev

and got:

Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
libboost-program-options-dev is already the newest version 
(1.74.0.3ubuntu6).
libboost-program-options-dev set to manually installed.
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

21.10 must have the 1.74 version.
