Start with the portfile.cmake entry at line 15 and reproduce `vcpkg install unixodbc:x64-linux-glibc`. Read the autoconf-x64-linux-glibc-out.log and autoconf-x64-linux-glibc-err.log alongside the x64-linux-glibc.cmake toolchain files. Done means the unixodbc port configures successfully on this triplet.
