Using BSD make, how can I apply different rules based on different
directories while using only a single makefile?


Ie, the appended Makefile results in the following compilations:

    gcc -DLIB -c lib/foo.c -o lib/foo.o
    gcc -DLIB -c lib/bar.c -o lib/bar.o
    gcc -DMCP -c mcp/baz.c -o mcp/baz.o

Is it possible to do something similar with BSD make?
