Makefile missing include path Although the path exists and defined

i have make file which i try to make them generic
but it keeps to compline it missing include directory
this is the makefile :

    CPPFAGS= -Wall -O0 -g -std=c++14
    INCLUDES = -I/home/vagrant/libuv/include -Isrc
    LIBS_DIRS = -L/home/vagrant/libuv/build
    LDFLAGS= -lssl -lcrypto
    LIB_STATIC = -Wl,--no-as-needed -Bstatic -luv_a -ldl -lpthread
    SOURCE = $(wildcard echo.cpp) \
             $(wildcard src/*.cpp)
    OBJ = $(SOURCE:.cpp=.o)
    DEP = $(OBJ:.o=.d)
    TARGET = myproj
    $(TARGET) : $(OBJ)
            $(CXX) $(CPPFLAGS) $(INCLUDES) -o $@ $^ $(LIBS_DIRS) $(LDFLAGS) $(LIB_STATIC)
    all: $(TARGET)
            rm -f $(OBJ) $(TARGET)
            rm -f $(DEP)
    .PHONY:all clean cleandep

when i make : make -n :


       make -n
    g++    -c -o echo.o echo.cpp
    g++    -c -o src/base64.o src/base64.cpp
    g++    -c -o src/Server.o src/Server.cpp
    g++    -c -o src/sha1.o src/sha1.cpp
    g++    -c -o src/Client.o src/Client.cpp
    g++  -I/home/vagrant/libuv/include -Isrc -o myproj echo.o src/base64.o src/Server.o src/sha1.o src/Client.o -L/home/vagrant/libuv/build -lssl -lcrypto  -Wl,--no-as-needed -Bstatic -luv_a -ldl -lpthread

when i invoke make , im getting this error:

    g++    -c -o echo.o echo.cpp
    In file included from src/Server.h:9:0,
                     from echo.cpp:1:
    src/Client.h:6:10: fatal error: uv.h: No such file or directory
     #include <uv.h>
    compilation terminated.
    make: *** [echo.o] Error 1

but the uv do exist in : /home/vagrant/libuv/include

gccmakedep(1)						      General Commands Manual						     gccmakedep(1)

gccmakedep - create dependencies in makefiles using 'gcc -M' SYNOPSIS
gccmakedep [ -sseparator ] [ -fmakefile ] [ -a ] [ -- options -- ] sourcefile ... DESCRIPTION
The gccmakedep program calls 'gcc -M' to output makefile rules describing the dependencies of each sourcefile, so that make(1) knows which object files must be recompiled when a dependency has changed. By default, gccmakedep places its output in the file named makefile if it exists, otherwise Makefile. An alternate makefile may be speci- fied with the -f option. It first searches the makefile for a line beginning with # DO NOT DELETE or one provided with the -s option, as a delimiter for the dependency output. If it finds it, it will delete everything following this up to the end of the makefile and put the output after this line. If it doesn't find it, the program will append the string to the makefile and place the output after that. EXAMPLE
Normally, gccmakedep will be used in a makefile target so that typing 'make depend' will bring the dependencies up to date for the make- file. For example, SRCS = file1.c file2.c ... CFLAGS = -O -DHACK -I../foobar -xyz depend: gccmakedep -- $(CFLAGS) -- $(SRCS) OPTIONS
The program will ignore any option that it does not understand, so you may use the same arguments that you would for gcc(1), including -D and -U options to define and undefine symbols and -I to set the include path. -a Append the dependencies to the file instead of replacing existing dependencies. -fmakefile Filename. This allows you to specify an alternate makefile in which gccmakedep can place its output. Specifying "-" as the file name (that is, -f-) sends the output to standard output instead of modifying an existing file. -sstring Starting string delimiter. This option permits you to specify a different string for gccmakedep to look for in the makefile. The default is "# DO NOT DELETE". -- options -- If gccmakedep encounters a double hyphen (--) in the argument list, then any unrecognized arguments following it will be silently ignored. A second double hyphen terminates this special treatment. In this way, gccmakedep can be made to safely ignore esoteric compiler arguments that might normally be found in a CFLAGS make macro (see the EXAMPLE section above). -D, -I, and -U options appearing between the pair of double hyphens are still processed normally.
