Did you manage to resolve this?

I am trying to build on CentOS 7.5 using the '2.1.0' branch, and seeing a
lot of "error: unknown type name" in src/tss2-esys/esys_crypto_gcrypt.c

The version available on CentOS repositories is:

libgcrypt-devel-1.5.3-14

I took a look at the releases and could not see a 2.0 (not entirely sure I
am looking at the right source?):

https://github.com/gpg/libgcrypt/releases

Any advice here on where to source the correct version and what that
version should be?
