Compile PHP-CPP extension on Windows

Question

I’m trying to develop a PHP extension with PHP-CPP on Windows. I was able to compile . a and . so of PHP-CPP with Mingw, however, when I compile the extension it does not find phpcpp. h.
My File Makefile:

NAME                    =   Teste
INI_DIR             =   /etc/php5/conf.d
EXTENSION_DIR           =   $(shell php-config --extension-dir)
EXTENSION           =   ${NAME}.so
INI                     =   ${NAME}.ini
COMPILER                =   g++
LINKER              =   g++
PHP_CONFIG          =   php-config
COMPILER_FLAGS      =   -Wall -c -O2 -std=c++11 -fpic -o
LINKER_FLAGS            =   -shared
LINKER_DEPENDENCIES =   -lphpcpp
RM                  =   rm -f
CP                  =   cp -f
MKDIR                   =   mkdir -p
SOURCES             =   $(wildcard *.cpp)
OBJECTS             =   $(SOURCES:%.cpp=%.o)
all:                    ${OBJECTS} ${EXTENSION}
${EXTENSION}:           ${OBJECTS}
                    ${LINKER} ${LINKER_FLAGS} -o $@ ${OBJECTS}         ${LINKER_DEPENDENCIES}
${OBJECTS}:
                    ${COMPILER} ${COMPILER_FLAGS} $@ ${@:%.o=%.cpp}
install:        
                    ${CP} ${EXTENSION} ${EXTENSION_DIR}
                    ${CP} ${INI} ${INI_DIR}

clean:
                    ${RM} ${EXTENSION} ${OBJECTS}

Folder structure:

main.cpp
Makefile
phpcpp. a
phpcpp.only

I added PHP-CPP files to Mingw’s Include folder and the error is now this:
