'openssl/evp.h' file not found OS x Mongodb

Question

Having a mare with this. I'm trying to install the latest PHP mongo DB Drivers. I've looked everywhere and tried everything suggested but it will not get passed this error:

---

In file included from /private/tmp/pear/install/mongodb/src/contrib/php-ssl.c:31:
/private/tmp/pear/install/mongodb/src/contrib/php-ssl.h:33:10: fatal error: 'openssl/evp.h' file not found
include <openssl/evp.h>
         ^
1 error generated.
make: *** [src/contrib/php-ssl.lo] Error 1
ERROR: `make' failed

---

My system / setup:

OS X El Capitain v 10.11.6
PHP 7.1.0
Apache

I'm using this command to install it: sudo pecl install mongodb

I've tried the:

$ brew install openssl
$ brew link openssl --force

but that no longer works...and any of the latest workarounds for that do not work either

I've even tried going "rootless" but to no avail.

This solution worked for me. If you don't already have openssl then first run brew install openssl. Then run:

$ cd /usr/local/include 
$ ln -s ../opt/openssl/include/openssl .
