Can't include SQLite libs in compile

Relevant part of configure.ac:

    PKG_CHECK_MODULES(SQLITE, [sqlite3 > $SQLITE_REQUIRED_VERSION])
    AC_SUBST([SQLITE3_CFLAGS])
    AC_SUBST([SQLITE3_LIBS])

Even without $SQLITE_REQUIRED_VERSION it still fails.
Relevant part of makefile.am:

    program_CFLAGS += @SQLITE3_CFLAGS@
    program_LDADD += @SQLITE3_LIBS@

I'm including sqlite3 in my header file:

    #include <sqlite3.h>

I'm getting errors such as this one:

    undefined reference to `sqlite3_prepare'

Any ideas why? I'm linking to it in the same way I'm including Gtk+,
which is linking correctly. I also browsed source code of other projects
to see how it was included and copied the code basically line-for-line.
I have installed all the packages I can think of related to sqlite but,
alas, still the pesky error.

Thanks in advance!
