[tpm2] TctiLdr_Initialize

I have been trying to use the TCTI for my programs and have even tried compiling the example code given in documentation but cannot seem to get it to compile.

https://www.mankier.com/3/Tss2_TctiLdr_Initialize

This page has example code for the library but it does not compile and warn against an undefined reference to the library.

Currently trying to compile a standalone file with this:
gcc testcheck.c -L=/usr/local/lib/ -ltss2-esys -ltss2-tcti-device -o testcheck
