BSD make question

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?
