fatal error: 'boost/test/unit_test.hpp' file not found

Question

I need to incorporate Boost.Test into my C++ program on macOS. Before doing so I first need to test makefiles using an example: https://github.com/jsankey/boost.test-examples The makefile included does not work so I modified it.

TARGETS=main hello suites fixtures assertions
INC=-I/usr/local/boost/include
LDFLAGS=-L/usr/local/lib -lboost_unit_test_framework
all: $(TARGETS)

test: $(TARGETS) $(addprefix run-,$(TARGETS))

main.o: main.cpp
    $(CXX) $< $(INC) -c
hello.o: hello.cpp
    $(CXX) $< $(INC) -c
suites.o: suites.cpp
    $(CXX) $< $(INC) -c
fixtures.o: fixtures.cpp
    $(CXX) $< $(INC) -c
assertions.o: assertions.cpp
    $(CXX) $< $(INC) -c
main: main.o
    $(CXX) $^ $(LDFLAGS) -o $@
hello: hello.o
    $(CXX) $^ $(LDFLAGS) -o $@
suites: suites.o
    $(CXX) $^ $(LDFLAGS) -o $@
fixtures: fixtures.o
    $(CXX) $^ $(LDFLAGS) -o $@
assertions: assertions.o
    $(CXX) $^ $(LDFLAGS) -o $@

run-%: %
    -./$^ --output_format=XML --log_level=test_suite > $(^)-report.xml

clean:
     rm $(TARGETS) *-report.xml

EDITED: Now compiling works well. Linking on the other hand causes an error, namely the following:
