## Compile ##

# Link c++ and CUDA compiled object files to target executable:
$(EXE) : $(OBJS)
	$(NVCC) $(OBJS) $(CUDA_LINK_LIBS) -o $@

# Force recompilation of header files by deleting main's object before make
remake : clean-main $(EXE)

# Compile main.cu file to object files:
$(OBJ_DIR)/%.obj : $(SRC_DIR)/%.cu
	$(NVCC) $(NVCC_FLAGS) -c $< -o $@

# Compile C++ source files to object files:
$(OBJ_DIR)/%.obj : $(SRC_DIR)/%.cpp $(INC_DIR)/%.hpp
	$(CC) $(CC_FLAGS) -c $< /Fo$@

# Compile CUDA source files to object files:
$(OBJ_DIR)/%.obj : $(SRC_DIR)/%.cu $(INC_DIR)/%.cuh
	$(NVCC) $(NVCC_FLAGS) -c $< -o $@

# Clean object from main only
clean-main:
	del /q $(OBJ_DIR)\\main.obj

# Clean objects in object directory.
