error LNK2019 unresolved external symbol dbbind referenced in function

Question

I'm trying to compile tds_fdw for Windows 64bit using Visual Studio Community 2017, but I'm getting the errors below.

The C/C++ Additional Include Directories are:

E:\Downloads\FreeTDS-1.00-x86\freetds-1.00\include
C:\Apps\postgres\pgsql-10.0\include\server\port\win32_msvc
C:\Apps\postgres\pgsql-10.0\include\server\port\win32
C:\Apps\postgres\pgsql-10.0\include
C:\Apps\postgres\pgsql-10.0\include\server
E:\Workspace\git\tds_fdw\include
%(AdditionalIncludeDirectories)

The Linker Input has Additional Dependencies:

C:\Apps\postgres\pgsql-10.0\lib\postgres.lib

What am I missing?

You failed to link to the FreeTDS .lib. You'll also need to ensure the associated .dll is in your PATH or copied to the same directory as the extension you built.
