Not too sure what you are doing there.

This should work all in the Makefile file, if using horse's erlang.mk:

PROJECT = test
include deps/horse/erlang.mk

deps/horse:
     git clone -n -- https://github.com/extend/horse $(DEPS_DIR)/horse
     cd $(DEPS_DIR)/horse ; git checkout -q master
     $(MAKE) -C $(DEPS_DIR)/horse

perfs: ERLC_OPTS += -DPERF=1 +'{parse_transform, horse_autoexport}'
perfs: clean deps deps/horse app
     $(gen_verbose) erl -noshell -pa ebin deps/horse/ebin \
         -eval 'horse:app_perf($(PROJECT)), init:stop().'

If you use a more recent erlang.mk it's much simpler, see 
https://github.com/ninenines/cowlib/blob/master/Makefile for example.
