Have you tried to follow these steps?
http://lemon.cs.elte.hu/trac/lemon/wiki/InstallAutotool#InstallfromSource

The ./configure command will show a summary of configuration options 
(they are automatically detected). This summary should contain the 
following line if you have GLPK properly installed:

GLPK support.................. : yes

If you have this line in the summary, finish the installation by 'make' 
and 'make install'.
