Extracting Name of File in CFLAGS

Hello Experts,

I have an elaborate recursive make system and I want an easy way to have
the name of the source file handy. To this end, I can use

.o : %.c
    $Q$(CC) -D BASENAME_FILE="$(shell basename $<)" $(CFLAGS) -c $< -o $@

However, this is probably not very neat as I want all variables to reflect

I am more comfortable in using something like ..
CFLAGS += -D BASENAME_FILE="$$(notdir $$<)"

in my top level Makefile and hope that this will be enough in my
multi-layer build system. However, this does not work. Can somebody help me
on this?
