How to use JSON-CPP?

Question

I strictly followed this documentation to install and use the jsoncpp library in my project: jsoncpp README

But I still have this problem with my compilation:

g ++ -W -Wall -Werror -c -o src / ModConnection.o src / ModConnection.cpp src / ModConnection.cpp: 15:23: fatal error: json / json.h: no such file or directory compilation completed.

This happens when I try to use #include <json/json.h>

Here is my Linux MAKEFILE:

CXX     =       g++
NAME    =       bin/server
SRCS    =       ./src/ModConnection.cpp\
                ./src/unixNetwork.cpp
OBJS    =       $(SRCS:.cpp=.o)
CXXFLAGS +=     -W -Wall -Werror
LDFLAGS =       -L ./src/jsoncpp-src-0.5.0/buildscons/linux-gcc4.5.1/src/lib_json/libjson_linux-gcc-4.5.1_libmt.a -I src/jsoncpp-src-0.5.0/include
RM      =       rm -f
$(NAME) :       $(OBJS)
$(CXX) $(LDFLAGS) -o $(NAME) $(OBJS)

all     :       $(NAME)

clean   :
                $(RM) $(OBJS)

fclean  :       clean
                $(RM) $(NAME)

re      :       fclean all

.PHONY  :       all clean fclean re

Thanks for the help.
