Makefiles: Writing list to screen

Shell Programming and Scripting
1

I have a make file and want to write some information and am doing

@echo "  RAYPK_LIBSRC = $(RAYPK_LIBSRC)"

The line of code produces

RAYPK_LIBSRC = ./source/library/raypk/time.f ./source/library/raypk/model.f ./source/library/raypk/tomo.f ./source/library/raypk/plt.f ./source/library/raypk/blkdat.f

I want the information displayed as follows

RAYPK_LIBSRC = ./source/library/raypk/time.f 
               ./source/library/raypk/model.f
               ./source/library/raypk/tomo.f 
               ./source/library/raypk/plt.f 
               ./source/library/raypk/blkdat.f

I have done this

    @echo "RAYPK_LIBOBJ ="
    for i in $(RAYPK_LIBOBJ); do \
      echo "                 $$i"; \
    done

producing

RAYPK_LIBOBJ =
for i in ./BUILD_DIR/obj/time.o ./BUILD_DIR/obj/model.o ./BUILD_DIR/obj/tomo.o ./BUILD_DIR/obj/plt.o ./BUILD_DIR/obj/blkdat.o; do \
      echo "                 $i"; \
    done
                 ./BUILD_DIR/obj/time.o
                 ./BUILD_DIR/obj/model.o
                 ./BUILD_DIR/obj/tomo.o
                 ./BUILD_DIR/obj/plt.o
                 ./BUILD_DIR/obj/blkdat.o

This is almost what I want. Got to remove the printing of the for loop. On addition, the first string

 ./BUILD_DIR/obj/time.o

needs to be next to

RAYPK_LIBOBJ =

And doing something like this

$(foreach s,$(RAYPK_LIBOBJ), @echo "                 $(s)"\n;)

gives errors

RAYPK_LIBOBJ =
                 ./BUILD_DIR/obj/time.on
/bin/sh: @echo: command not found
/bin/sh: @echo: command not found
/bin/sh: @echo: command not found
/bin/sh: @echo: command not found
make: *** 
 Error 127

I have made some progress on this

    @echo "RAYPK_LIBOBJ = $(word 1, $(RAYPK_LIBOBJ))"
    @$(foreach s,$(RAYPK_LIBOBJ), echo "               $(s)";)

This produces

RAYPK_LIBOBJ = ./BUILD_DIR/obj/time.o
               ./BUILD_DIR/obj/time.o
               ./BUILD_DIR/obj/model.o
               ./BUILD_DIR/obj/tomo.o
               ./BUILD_DIR/obj/plt.o
               ./BUILD_DIR/obj/blkdat.o

So the last thing remaining is not to print again

./BUILD_DIR/obj/time.o

when dong the foreach loop.

I like

echo ... | while read l ;do ...; done
