Well, no one else is chiming in, so I guess you are stuck with me.  Maybe a 
Windows user will help out?

Have you actually installed glpk?  If so, the library should be in a default 
location and ready to be linked against.  If you haven't done a 'make install' 
for GLPK, I'd recommend you try that next and then figure out where the library 
file goes (is it a .dll for Windows?).  You shouldn't even need a -L flag if 
the library is installed in a default location, though you can supply one 
anyway if you know where the installed library lives.

>From the GLPK manual:

If the library is installed in the default location /usr/local/lib, the 
following typical command may be used to link, say, the example C program 
described above against with the library: 
$ gcc sample.o -lglpk -lm 
If the GLPK library is not in the default location, the corresponding 
directory containing it should be made known to the linker through -L 
option, for example: 
$ gcc -L/foo/bar/glpk-4.15 sample.o -lglpk -lm 



Keep us posted.
