I have the following file just sitting in PETSC_DIR/Makefile.user.  I
build code with

$ make -f $PETSC_DIR/Makefile.user ex56

from any directory (no need to have a local Makefile; just copy the
example wherever you want or leave it in the source directory if you
insist).  I like this because there are no includes, thus no mysterious
make variables, and it's clear how one would compose it with other
packages that provide pkgconfig files.

$ cat $PETSC_DIR/Makefile.user
PETSc.pc := $(PETSC_DIR)/$(PETSC_ARCH)/lib/pkgconfig/PETSc.pc

CC := $(shell pkg-config --variable=ccompiler $(PETSc.pc))
CXX := $(shell pkg-config --variable=cxxcompiler $(PETSc.pc))
FC := $(shell pkg-config --variable=fcompiler $(PETSc.pc))
CFLAGS := $(shell pkg-config --variable=cflags_extra $(PETSc.pc)) $(shell pkg-config --cflags-only-other $(PETSc.pc))
CPPFLAGS := $(shell pkg-config --cflags-only-I $(PETSc.pc))
LDFLAGS := $(shell pkg-config --libs-only-L --libs-only-other $(PETSc.pc))
LDFLAGS += $(patsubst -L%, $(shell pkg-config --variable=ldflag_rpath $(PETSc.pc))%, $(shell pkg-config --libs-only-L $(PETSc.pc)))
LDLIBS := $(shell pkg-config --libs-only-l $(PETSc.pc)) -lm

print:
	@echo CC=$(CC)
	@echo CFLAGS=$(CFLAGS)
	@echo CPPFLAGS=$(CPPFLAGS)
	@echo LDFLAGS=$(LDFLAGS)
	@echo LDLIBS=$(LDLIBS)
