Using makefile to link cimgui to project? - c++

Question

I have a c project and I'm trying to link the C binding for imgui to it using Makefiles but I'm having some trouble. I've already generated the .dll using cmake in a build folder, these are the contents of it:
C:\path\to\cimgui\build:
-CMakefiles
-cimgui.dll
-cmake_install.txt
-CMakeCache.txt
-libcimgui.dll.a
-Makefile
and this is my makefile
PROJ := proj
TARGET := $(PROJ)
OBJ := sub.o main.o
INCLUDE_PATH := -IC:\path\to\SDL2 -IC:\path\to\cimgui
LIB_PATH := -LC:\path\to\SDL2\lib -LC:\path\to\cimgui\build
LINKER_FLAGS := -lSDL2 -lopengl32 -lcimgui -lcimgui.dll
CFLAGS := $(INCLUDE_PATH)
.PHONY : build clean
build : $(TARGET).exe
$(TARGET).exe: $(OBJ)
gcc $^ $(LIB_PATH) $(LINKER_FLAGS) -o $#
sub.o: sub.c sub.h
gcc -c $(CFLAGS) $< -o $#
main.o: main.c sub.h
$(CC) $(CFLAGS) $< -o $#
clean :
#rm -fv *.o
#rm -fv *.exe
and this is my main.c project
#define CIMGUI_DEFINE_ENUMS_AND_STRUCTS
#include "cimgui.h"
#include <stdio.h>
#include <stdlib.h>
#include <SDL.h>
#include <SDL_opengl.h>
int main(int argc, char ** argv)
{
return 0;
}
This is the error I get when i try to compile my makefile:
c:/mingw/bin/../lib/gcc/mingw32/6.3.0/../../../../mingw32/bin/ld.exe: cannot find -lcimgui.dll
