编译无法找到头文件

[OneOnce]

代码目录结构：

Makefile在dll01里面，编译也是来这里编译。
Public.h

#ifndef __PUBLIC_H__
#define __PUBLIC_H__
#define PI 3.1415926
#endif // !__PUBLIC_H__

TestLib.h
测试包含上一层头文件，如包含Public.h：#include <dll01/Public.h>

#ifndef __TESTLIB_H__
#define __TESTLIB_H__
#include <dll01/Public.h>
class TestLib
{
public:
    TestLib();
    virtual ~TestLib();
public:
    int TestSum(int a, int b);
};
#endif // ! __TESTLIB_H__

TestLib.cpp

#include "TestLib.h"
TestLib::TestLib() {
}
TestLib::~TestLib() {
}
int TestLib::TestSum(int a, int b) {
    return a + b;
}

Makefile

TARGET := libMyMath.so
TARGET_PATH :=../ 
CC      := g++
LIBS    := 
LDFLAGS := 
DEFINES :=
INCLUDES := -I..
CFLAG  := -g -Wall -O3 -std=c++11 $(DEFINES) $(INCLUDES)
CXXFLAGS:= $(CFLAGS)
VPATH = . ./subdir
SOURCE   := $(wildcard *.cpp) $(wildcard subdir/*.cpp)
SRC_WITHOUTDIR:= $(notdir $(SOURCE))
OBJS     := $(patsubst %.c,%.o,$(patsubst %.cpp,%.o,$(SRC_WITHOUTDIR)))

$(TARGET) : $(OBJS)
	$(CC) -shared -o $@ $(OBJS) $(LDFLAGS) $(INCLUDES)
%.o : %.cpp
	$(CC) $(CXXFLAGS) -fpic -c $< -o $@ $(LDFLAGS) $(LIBS)

.PHONY : clean
clean:
	rm -f *.o
	rm -f $(TARGET)

通过INCLUDES := -I..让包含目录指向dll01的上一层
编译提示找不到Public.h
错误信息：
g++ -fpic -c ./subdir/TestLib.cpp -o TestLib.o
In file included from ./subdir/TestLib.cpp:1:0:

CXXFLAGS:= $(CFLAGS)改成 CXXFLAGS:= $(CFLAG)多了一个S

没人来领分么
