‘string’ in namespace ‘std’ does not name a type in cstring

[techwday]

When trying to compile in Ubuntu 21.04 I get the following error with regards to cstring. If I add #include to MerkleCommitment.hpp then the library compiles.

In file included from src/protocols/Ali/common_details/common.hpp:4,
                 from src/protocols/Ali/common_details/common.cpp:1:
src/protocols/common/CryptoCommitment/MerkleCommitment.hpp:17:10: error: ‘string’ in namespace ‘std’ does not name a type

Just add the include please #include <string>, it solves the problem.
