Makefile for linking opencv.framework (I'm not using cmake) - c++

Question

I use opencv in my project, and now I compile the project into a static library using makefile, but always output 'fatal error: 'cv.h' file not found'. I have searched this site and elsewhere, it's not what I need. I only know a little makefile syntax. What should I do?
Makefile
LIBS_DIR = ./lib/
OBJS_DIR = ./obj/
DEPENDENT_DIR = ./dependent/
HEADER_PATH = -I./include -I./implement -I.
LIB_PATH = -L./lib
SRCDIRS := $(patsubst ./%, %, $(shell find . -type d))
SRCS_CXX := $(foreach dir, $(SRCDIRS), $(wildcard $(addprefix $(dir)\/*, .cpp)))
OBJS := $(SRCS_CXX:.cpp=.o)
%.o: %.cpp
#echo "---------- .o begin ----------"
$(CXX) -c $< $(HEADER_PATH)
$(CXX) -o $# $^ $(LIB_PATH)
mv $# $(OBJS_DIR)
%.d: %.cpp
#echo "---------- dependent begin ----------"
#set -e; \
rm -f $#; \
$(CXX) -MM $< > $#.tmp; \
sed 's,\($*\)\.o[ :]*,\1.o $# : ,g' < $#.tmp > $#; \
rm -f $#.tmp
mv $# $(DEPENDENT_DIR)
-include $(DEPS)
.PHONY: clean
clean:
rm -f obj/*.o lib/*.a dependent/*.d
rm -rf SunWS_cache
In my file
#include <cv.h>
#include <cxcore.h>
#include <highgui.h>
File directory
Used makefile
New error
I modified the HEADER_PATH like HEADER_PATH = -I./include/opencv -I./include/opencv2 -I./implement -I. but a new error appeared, fatal error: 'opencv2/core/core_c.h' file not found.
I try to add a new subfolder path like -I./include/opencv -I./include/opencv2 -I./include/opencv2/core -I./implement -I. this error is still being output, -I command doesn't automatically find the path to the subfolder? am I doing anything wrong?

Answer 1

Your header paths are HEADER_PATH = -I./include -I./implement -I.
Inside the include folder you show in the attachment you have 2 subfolders opencv and opencv2.
When including the cv.h file is included directly without the subfolders.
For the compiler to find the files you either need to add the subfolders on the HEADER_PATH like HEADER_PATH = -I./include/opencv -I./include/opencv2 -I./implement
or you need to #include <opencv/cv.h>, that if cv.h is directly inside the opencv subfolder.
Side note: you have a typo in the folder denpendent

Answer 2

Finally, I solved this error and compiled successfully, I still use CMake. but after I successfully compiled with CMake, I can use the Makefile again to compile. I think it was my own mistake, #zomeck's answer helped me.
This is my CMakeLists.txt
cmake_minimum_required(VERSION 3.2)
project(library_name)
add_definitions(-Wall)
set(OPENCV_PATH ../sdk3/opencv3.0.0)
set(OPENCL_PATH ../sdk3/opencl)
link_directories(
${OPENCL_PATH}/bin
${OPENCV_PATH}
)
link_libraries(
${OPENCV_PATH}/opencv2.framework
${OPENCL_PATH}/bin/OpenCL.DLL
)
include_directories(
./
./implement
${OPENCV_PATH}/include
${OPENCV_PATH}/include/opencv
${OPENCL_PATH}/include/CL
)
set(SOURCES_FILES
HS_Process.cpp
implement/iclear/H_Proc.cpp
)
add_library(library_name STATIC ${SOURCES_FILES})
target_link_libraries(library_name opencv2 OpenCL)
New Makefile after #zomeck's answer
# The following is modified
SDK_PATH = ../sdk3
OPENCL_PATH = ../sdk3/opencl
OPENCV_PATH = ../sdk3/opencv3.0.0/include
vpath = %.h implement : %.h $(OPENCV_PATH) : %.h $(OPENCV_PATH)/opencv : %.h $(OPENCL_PATH) : %.h $(CALCTIME_PATH)
HEADER_PATH = \
-I. \
-I./implement \
-I$(OPENCV_PATH) \
-I$(OPENCV_PATH)/opencv \
-I$(OPENCV_PATH)/opencv2 \
-I$(OPENCL_PATH)/include/CL \
%.o: %.cpp
#echo "---------- .o begin ----------"
$(CXX) $(CXXFLAGS) -c $(HEADER_PATH) $< -o $#
mv $# $(OBJS_DIR)
