How do I build xdebug with the correct php binaries

I'm running a sandboxed bitnami instance on php 7.1.2, and it didn't come with xdebug. No big deal I just download xdebug 2.5.1 and compile it myself. I followed the compilation instructions (https://xdebug.org/docs/install), I used the phpize binary that was shipped in my bitnami instance, and it gave me the correct result:

Configuring for:
PHP Api Version:         20160303
Zend Module Api No:      20160303
Zend Extension Api No:   320160303

I followed with ./configure and make, everything is fine, the xdebug.so extension is correctly built and I move it to my bitnami files and add it to my php.ini. The extension is not loaded and I get this error:

Xdebug requires Zend Engine API version 220121212.
The Zend Engine API version 320160303 which is installed, is newer.

220121212 is the version that came with my OS, I'm guessing it's somewhere in /usr/bin or something. So even if I use the correct phpize binary, it still builds with the wrong version. How do I force it to build with the correct php binaries? (which are in my bitnami files)

> ~/bitnami/php/bin/phpize --version
Configuring for:
PHP Api Version:         20160303
Zend Module Api No:      20160303
Zend Extension Api No:   320160303

> phpize --version
Configuring for:
PHP Api Version:         20121113
Zend Module Api No:      20121212
Zend Extension Api No:   220121212

EDIT: I should specify that my OS is OS X 10.10.5

Solution

Found it, I had to run ./configure with the correct options as such:

./configure --with-php-config=/Users/boux/bitnami/php/bin/php-config
