Have a look at the `ld' info page:
,----[ (info "(ld)Options") ]
| `-lARCHIVE'
| `--library=ARCHIVE'
| Add archive file ARCHIVE to the list of files to link. This
| option may be used any number of times. `ld' will search its
| path-list for occurrences of `libARCHIVE.a' for every ARCHIVE
| specified.
|
| On systems which support shared libraries, `ld' may also search
| for libraries with extensions other than `.a'. Specifically, on
| ELF and SunOS systems, `ld' will search a directory for a library
| with an extension of `.so' before searching for one with an
| extension of `.a'. By convention, a `.so' extension indicates a
| shared library.
|
| The linker will search an archive only once, at the location
| where it is specified on the command line. If the archive
| defines a symbol which was undefined in some object which
| appeared before the archive on the command line, the linker will
| include the appropriate file(s) from the archive. However, an
| undefined symbol in an object appearing later on the command line
| will not cause the linker to search the archive again.
|
| See the `-(' option for a way to force the linker to search
| archives multiple times.
|
| You may list the same archive multiple times on the command line.
|
| This type of archive searching is standard for Unix linkers.
| However, if you are using `ld' on AIX, note that it is different
| from the behaviour of the AIX linker.

You can add the directory where `ld' should look for libabc with
-L/dir/of/libabc/.
