It doesn't, I do have libtpm2tss.so (same on my Ubuntu 16.04.5 VM
though).
However, if I link the libtpm2tss.so -> tpm2tss.so the engine is picked
up:
$ sudo ln -s /usr/local/lib/openssl/engines/libtpm2tss.so
/usr/local/lib/openssl/engines/tpm2tss.so
$ OPENSSL_ENGINES=/usr/local/lib/openssl/engines openssl engine -t -c
tpm2tss
(tpm2tss) TPM2-TSS engine for OpenSSL
 [RSA, RAND]
     [ available ]

or indeed if I use libtpm2tss as the engine name:

$ OPENSSL_ENGINES=/usr/local/lib/openssl/engines openssl engine -t -c
libtpm2tss
(libtpm2tss) TPM2-TSS engine for OpenSSL
Loaded: (tpm2tss) TPM2-TSS engine for OpenSSL
 [RSA, RAND]
     [ available ]

Thanks,

Joshua
