This might be libraries getting mixed up.

Do you maybe also have two boost versions installed, one from /Ubuntu and one 
unter /usr/local.
You can run
ccmake . 
in the build dir and then press 't'  to toggle to the advanced view and check 
the boost library path.
You can also use ldd to query library resolution on the Espresso shared objects:

On Ubuntu 20, I get /lib/x86_64-linux-gnu/libboost_mpi.so.1.71.0 as the 
resolution for boost mpi.
