Linking object build in sub directory in makefile

I am trying to link all object I have build in my makefile during the executable compilation, but I cant seem to automate selecting the build directory.

I have tried:

test: $(OBJECTS)
    $(CC) $(CFLAGS) $(INCDIR) $(LIBDIR) $(BUILDDIR)/$^ test.cpp -o test.exe

The problem is that $(BUILDDIR)/$^ only inserts $(BUILDDIR) in front of the first object file.

How should I be doing this?

If you want to add $(BUILDDIR) to all the prerequisites directly in the command, then you can do:

test: $(OBJECTS)
    $(CC) $(CFLAGS) $(INCDIR) $(LIBDIR) $(addprefix $(BUILDDIR)/,$^) test.cpp -o test.exe

However, setting up make rules this way means you're not tracking dependencies correctly. I think what you actually want is this:

test: $(addprefix $(BUILDDIR)/,$(OBJECTS))
    $(CC) $(CFLAGS) $(INCDIR) $(LIBDIR) $^ test.cpp -o test.exe
