config.m4 file is missing when compiling gmp php extension in lampp suite

Question

I am trying to compile the gmp for lampp suite with php 7.1.7 with api version 20160303 . I downloaded gmp-6.1.2.tar.bz2 used
bzip2 -dk gmp-6.1.2.tar.bz2
to get tar file then tar -xvvf gmp-6.1.2.tar then cd gmp-6.1.2/.
When i run
/opt/lampp/bin/phpize (i am using lampp suite for dev), I got this

Cannot find config.m4. 
Make sure that you run '/opt/lampp/bin/phpize' in the top level source directory of the module

I am trying to compile gmp for php7.1.7.

Without running /opt/lampp/bin/phpize, and following these steps

./configure
make
make test
make install

Its all compiling without any error with api version 20151012 but my php say its needs 20160303

Running php on console, I am getting this:

PHP Warning:  PHP Startup: gmp: Unable to initialize module
Module compiled with module API=20151012
PHP    compiled with module API=20160303
These options need to match
 in Unknown on line 0

Warning: PHP Startup: gmp: Unable to initialize module
Module compiled with module API=20151012
PHP    compiled with module API=20160303
These options need to match
 in Unknown on line 0

I have download gmp source files from https://gmplib.org/download/gmp/gmp-6.1.2.tar.bz2 — Bhuvaneshwar Nagaraj, Oct 12 '17 at 07:43
this is not the PHP extension, this is the GMP library, PHP extension uses the GMP library — hassan, Oct 12 '17 at 07:57
the PHP_SRC comes with gmp extension by default, but you still needs to enable it while you are compiling the PHP itself with the flag `--with-gmp` — hassan, Oct 12 '17 at 07:59
I didn't compile php, check question, I am using lampp suite — Bhuvaneshwar Nagaraj, Oct 12 '17 at 08:01

based on your comments, in order to compile a specific version of GMP extension, you will need to clone the PHP-SRC repository, and compile the PHP GMP extension.

git clone git@github.com:php/php-src.git

you may clone a the targeted branch rather that cloning the whole repository

git clone -b PHP-7.1.7 git@github.com:php/php-src.git --depth 1

then go to the GMP extension directory & phpize the extension and complete your compilation steps.

cd php-src/ext/gmp
phpize
./configure
make
sudo make install

I also want to add that if compiling extension with lampp suite, provide php-config path while using `./configure --with-php-config=PATH_PHP_CONFIG` – Bhuvaneshwar Nagaraj Oct 12 '17 at 09:27
