Линукс правильный флаг для передачи местоположения gcc mcrypt.h

Я собрал libmcrypt от источника до /home/mybin/... с последующим подтверждением в качестве местоположения необходимых файлов.

/home/mybin/include/mcrypt.h
/home/mybin/include/mutils/mcrypt.h
/home/mybin/lib/libmcrypt.so ...> 4.4.8
/home/mybin/bin/libmcrypt-config

Когда я пытаюсь ./configure для php7, используя следующие параметры, я получаю сообщение об ошибке configure: error: mcrypt.h not found. Please reinstall libmcrypt.

Какие флаги я неправильно использую, чтобы указать gcc посмотреть в ../include каталог для mcrypt.h

./configure \
CC=/home/mybin/bin/gcc \
CPPFLAGS="-I/home/mybin/include" \
LDFLAGS="-L/home/mybin/lib" \
LIBS="-lmcrypt" \
--prefix=/home/_cgi/php7 \
--bindir=/home/mybin/bin \
--libdir=/home/mybin/lib \
--includedir=/home/mybin/include \
--with-mcrypt=/home/mybin/lib

от configure --help я получил

Some influential environment variables:
CC          C compiler command
CFLAGS      C compiler flags
LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
nonstandard directory <lib dir>
LIBS        libraries to pass to the linker, e.g. -l<library>
CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
you have headers in a nonstandard directory <include dir>
CPP         C preprocessor
YACC        The `Yet Another Compiler Compiler' implementation to use.
Defaults to the first program found out of: `bison -y', `byacc',
`yacc'.
YFLAGS      The list of arguments that will be passed by default to $YACC.
This script will default YFLAGS to the empty string to avoid a
default value of `-d' given by some make applications.
CXX         C++ compiler command
CXXFLAGS    C++ compiler flags
CXXCPP      C++ preprocessor
