Linker error with SQlite3 and Postgresql:

I am trying to build a (CLI) 'C' program that requires access to either SQlite3 or Postgresql. I include the appropriate '.h' files, but when I execute a build a link error occurs indicating no access to particular functions within the libraries of the respective databases.

I have been able compile the same code using 'gcc' with a simple command like $gcc -l sqlite3.

I've tried to get Xcode to 'point' to the appropriate library/framework, but it is a), not listed, and b), there seems to be no way to add anything textually - such as typing in the location of the libraries.

Does anyone know how I add or can 'point' to a library/framework that is not listed within the Xcode environment?
