 Replying to [comment:1 neteler]:
 > A grass-config would probably facilitate the development of an automated
 GRASS-Addons integration script (which downloads Addon from SVN, then
 compiles it according to the local settings)

 Add-ons should get all the configuration information they need from the
 *.make files.

 Replying to [comment:2 hamish]:

 $GISBASE/include/Make/* as needed.

 Parsing *.make won't work; given that values can be arbitrary make
 expressions, you would need to duplicate make's functionality exactly.

 You would be better off just invoking make on a suitable Makefile, e.g.:
 {{{
 $ cat foo.mk
 MODULE_TOPDIR = $(GISBASE)
 include $(MODULE_TOPDIR)/include/Make/Vars.make
 var.%:
         @echo $($*)

 $ make -f foo.mk var.PNGLIB
 -lpng -lz -lm
 }}}

 last two)

 None of them, really. GRASS isn't a single library; you would need
 separate options for each component.
