XCode IDE Library settings versus gcc make files - xcode

Question

I have spent a lot of time researching how to compile a simple PostgreSQL test application written in C and I've got it to compile, run and connect to the PostgreSQL database that comes with Mavericks Server om my Mac Mini running OS X 10.9.3.
Then I decided to try using the Xcode IDE to compile and debug the same PostgreSQL code however, in Xcode I am getting references to Postgres methods listing 7 issues related to "Apple Mach-O Linker (ld) Error", including _PQclear, _PQconnectdb, PQerrorMessage, _PQexec, _PQfinish, _PQprint, _PQstatus. The final error is related to Linker command failed with exit code 1 (use -v to see invocation). Note: I'm not sure where to add the -ld parameters in the Xcode IDE or where to put the -v to find out more.
I have read many of the Stack Overflow items but most of them relate to iOS rather than OSX however I tried to figure out how to use many of those suggestions. Unfortunately I still am not able to figure out where to add the ld (LD) item for postgres similar to what I have in my make file. I tried adding and changing different settings on the Build Phases in the Xcode IDE but I keep getting these 8 issues.
In my code that I'm trying to compile from Xcode I changed one line to point to the location where the libpq-fe.h is as follows but I'm not sure if this is the correct or best approach:
#include </Applications/Server.app/Contents/ServerRoot/usr/include/libpq-fe.h>
Here is my makefile that compiles using make pg_test
## File: makefile
## Rules to create libpq sample application
LDLIBS += -L/Applications/Server.app/Contents/ServerRoot/usr/lib/postgresql9.1/ -lpq
CFLAGS += -c -v -g -I/Applications/Server.app/Contents/ServerRoot/usr/include/
LDFLAGS += -g
pg_test: pg_test.o
Here is my pg_test.c code
// File: pg_test.c
#include <stdlib.h>
#include <libpq-fe.h>
void process_query (PGconn * connection, const char * query_text ) {
PGresult * result;
PQprintOpt options = {0};
if(( result = PQexec ( connection, query_text )) == NULL ) {
printf( "%s\n", PQerrorMessage ( connection ));
return;
}
options.header = 1;
options.align = 1;
options.fieldSep = "|";
PQprint (stdout, result, &options );
PQclear ( result );
}
int main ( ) {
PGconn * connection;
char * dbarg = "user=jerry password=test dbname=jletter hostaddr=127.0.0.1 port=5432";
connection = PQconnectdb(dbarg);
if( PQstatus( connection ) != CONNECTION_OK )
printf( "%s\n", PQerrorMessage( connection ));
else {
process_query( connection, "SELECT * FROM friends" );
}
PQfinish ( connection );
exit (0);
}
Any help would be greatly appreciated.
