链接库没有在makefile中正确设置

我有下面的makefile，我用它来编译一个简单的项目(这个例子只有一个.cpp，包括一些外部头文件和一个共享库):

ifndef _ARCH
_ARCH := $(shell uname -m)
export _ARCH
endif
NAME := Test
MAJOR := 1
MINOR := 5
VERSION := v$(MAJOR)_$(MINOR)
TARGET := $(NAME)_$(VERSION).o
SRCEXT   := cpp
SRCDIR   := src
INCPATH  := inc
OBJDIR   := obj
BINDIR   := bin
BIN_DEBUGDIR   := $(BINDIR)/debug
API_DIR := /DEM_API/Multibody/DEMCoupling

INCLUDES := -I. 
            -I$(INCPATH) 
            -I$(API_DIR)
# C++ compiler flag
CXXFLAGS := -Wall -march=native $(INCLUDES) -c
# Linker parameter flags
# Linker library flags
LIBDIRS  := -L$(API_DIR)/lib
LDLIBS   := -lEDEMCouplingClientV2_2_0
LDFLAGS  := $(LIBDIRS) 

SRCS    := $(shell find $(SRCDIR) -name '*.$(SRCEXT)')
SRCDIRS := $(shell find . -name '*.$(SRCEXT)' -exec dirname {} ; | uniq)
OBJS    := $(patsubst %.$(SRCEXT),$(OBJDIR)/%.o,$(SRCS))

ifeq ($(SRCEXT), cpp)
CC       = $(CXX)
else
CXXFLAGS  += -std=gnu99
endif
.PHONY: all debug release clean distclean 

all: $(BINDIR)/$(TARGET)
# Build debug library
debug: CXXFLAGS += -g
debug: clean $(BIN_DEBUGDIR)/$(TARGET)

# strip all symbols from release verison
release: LDFLAGS += -s 
release: CXXFLAGS += -O2
release: $(BINDIR)/$(TARGET)
$(BINDIR)/$(TARGET): buildrepo $(OBJS)
    @mkdir -p `dirname $@`
#   @echo "Linking $@..."
    $(CC) $(LDFLAGS) $(OBJS) $(LDLIBS) -o $@ 
#   @echo "$@ sucessfully built."
$(BIN_DEBUGDIR)/$(TARGET): buildrepo $(OBJS)
    @mkdir -p `dirname $@`
#   @echo "Linking $@..."
    $(CC) $(LDFLAGS) $(OBJS) $(LDLIBS) -o $@ 
#   @echo "$@ sucessfully built."
$(OBJDIR)/%.o: %.$(SRCEXT)
#   @echo "Generating dependencies for $<..."
    $(call make-depend,$<,$@,$(subst .o,.d,$@))
#   @echo "Compiling $<..."
    $(CC) $(CXXFLAGS) $< -o $@
clean:
    $(RM) -r $(OBJDIR)
distclean: clean
    $(RM) -r $(BINDIR)/$(TARGET)
    $(RM) -r $(BIN_DEBUGDIR)/$(TARGET)
buildrepo:
    $(call make-repo)
define make-repo
   for dir in $(SRCDIRS); 
   do 
    mkdir -p $(OBJDIR)/$$dir; 
   done
endef

# usage: $(call make-depend,source-file,object-file,depend-file)
define make-depend
  $(CC) -MM       
        -MMD      
        -MF $3    
        -MP       
        -MT $2    
        $(CXXFLAGS) 
        $(LDFLAGS) 
        $1
endef

它成功地编译了这个项目，但是当我试图从终端运行可执行文件时，我只得到以下错误:

./Test_v1_5.o: error while loading shared libraries: libEDEMCouplingClientV2_2_0.so: cannot open shared object file: No such file or directory

我不明白为什么。

作为测试，我在代码块中设置了相同的项目并编译了发布版本，它工作得很好。

这是我的makefile的构建输出:

for dir in ./src ./old; do mkdir -p obj/$dir; done

g++ -L/home/DEM_API/Multibody/DEMCoupling/lib  obj/src/Test_v11.o -lDEMCouplingClientV2_2_0 -o bin/Test_v1_5.o 

下面是code::blocks:

有谁知道makefile中可能出现的问题吗?非常感谢帮助!
