No rule to make target but the rule exists - makefile

Question

I wanted to write some Makefile for testing C code via Unity test framework.
However when I want to test it I get the message make: *** No rule to make target 'unity_build/results/test_unity_dumb_example.unity_res', needed by 'unity_test'. Stop. . I can not figure out what is wrong because there is the rule for files that match the pattern: $(UNITY_PATHR)%.unity_res:.
Here is beginning of my Makefile:
UNITY_PATHU = ${UNITY_INSTALL_DIR}/
UNITY_PATHS = src/
UNITY_PATHS += src/unity_dumb_example/
UNITY_PATHT = unity_test/
UNITY_PATHB = unity_build/
UNITY_PATHD = unity_build/depends/
UNITY_PATHO = unity_build/objs/
UNITY_PATHR = unity_build/results/
UNITY_BUILD_PATHS = $(UNITY_PATHB) $(UNITY_PATHD) $(UNITY_PATHO) $(UNITY_PATHR)
# Tell compiler where to look for all test files
UNITY_SRCT = $(wildcard $(UNITY_PATHT)*.c)
UNITY_COMPILER=gcc -c
UNITY_LINKER=gcc
UNITY_DEPEND=gcc -MM -MG -MF
UNITY_CFLAGS=-I. -I$(UNITY_PATHU) -I$(UNITY_PATHS) -DTEST
UNITY_RESULTS = $(patsubst $(UNITY_PATHT)test_%.c,$(UNITY_PATHR)test_%.unity_res,$(UNITY_SRCT))
unity_test: $(UNITY_BUILD_PATHS) $(UNITY_RESULTS)
#echo "-----------------------\nIGNORES:\n-----------------------"
#echo `grep -s IGNORE $(UNITY_PATHR)*.unity_res`
#echo "-----------------------\nFAILURES:\n----------------------"
#echo `grep -s FAIL $(UNITY_PATHR)*.unity_res`
#echo "\nDONE"
$(UNITY_PATHR)%.unity_res: $(UNITY_PATHB)%.out
./$< > $# 2>&1
In GNU make manual I have read
The target is a pattern for matching file names; the ‘%’
matches any nonempty substring, while other characters match only themselves.
I do not understand why make complains because there is no misspell.
EDIT:
After full clean the output is as follows:
mkdir -p unity_build/
mkdir -p unity_build/depends/
mkdir -p unity_build/objs/
mkdir -p unity_build/results/
make: *** No rule to make target 'unity_build/results/test_unity_dumb_example.unity_res', needed by 'unity_test'. Stop.
All the needed paths exist.
When I run make in debug mode -d I can see that make is trying pattern rule with stem test_test_unity_dumb_example instead of test_unity_dumb_example, for example:
Trying pattern rule with stem 'test_test_unity_dumb_example'
test_test_ was my mistake but I have fixed it. I still can't make it work.
When I run with -p I can find something like this in the output:
# Implicit Rules
unity_build/results/%.unity_res: unity_build/%.out
# recipe to execute (from 'Makefile.unity', line 30):
./$< > $# 2>&1
SOLVED
The problem was with the prerequisite of the prerequisite of the $(UNITY_PATHB)%.out. Precisely, path to one crucial source file was ${UNITY_INSTALL_DIR}/src instead of ${UNITY_INSTALL_DIR}/ .
However I still find it weird that make was complaining about the rule to target that is 2 level above the target that could not be built.
