[Omake] Newbie: removing quotes for command

[Hugo Ferreira]

Hello,

Apologies for the very basic question I have but I just cannot seem to 
solve it. I am including a file with omake code as follows:

%.cmx %.o: %.ml
	$(OCAMLOPT) $(INCLUDE) $(OFLAGS) -c $<

In the main file I include it with:
include ../OMakefile.shared

Now I have the following variable

INCLUDES += ../res_stck ../qalist ../term ../symbl_tbl ../compile

and would like to use it to set INCLUDE (used in ../OMakefile.shared) to:

INCLUDE = -I ../res_stck -I ../qalist -I ../term -I ../symbl_tbl -I 
../compile

I have used:
	INCLUDE = $(addprefix -I , $(INCLUDES))
and
	INCLUDE = $(mapprefix -I , $(INCLUDES))

But when the target executes I get:

ocamlc "-I " . "-I " ../res_stck "-I " ../qalist "-I " ../term "-I " 
../symbl_tbl "-I " ../compile -dtypes -g -c parser.mli

...which breaks. How do I get rid of the quotes to obtain:

ocamlc -I . -I ../res_stck -I ../qalist -I ../term -I ../symbl_tbl -I 
../compile -dtypes -g -c parser.mli

I have even attempted to use my own function:

F(X, Y) =
	T =
	foreach (Z, $(X))
		T = $(T)$(Y)$(Z)

#INCLUDE = $( F $(INCLUDES), -I )

But to no effect.

Can anyone also explain how/why/when values are converted to/from a string?

TIA.
Hugo F.
