libpki 0.8.9 fails to build on CentOS 8

[MagellanTX]

I'm trying to build the libpki library on CentOS 8 but part-way into the make, it stops with the error below. My guess is that it has something to do with openssl (1.1.1f), but not sure.

It builds fine on CentOS 7

libpki doesn't build with OpenSSL 1.1.1f because some of the API has become opaque. I suspect it wants 0.9.x. So if you can find a way to provide the earlier release to configure that might solve it.
