问题
I am trying to install a PHP MongoDB driver but the installation is failing because it cannot locate the OpenSSL.
/Users/username/mongo-php-driver/src/libmongoc/src/mongoc/mongoc-crypto-openssl.c:24:10: fatal error: 'openssl/sha.h' file not found
#include <openssl/sha.h>
^
1 error generated.
make: *** [src/libmongoc/src/mongoc/mongoc-crypto-openssl.lo] Error 1
I read that this has something to do with the latest version of MacOS? Is there a way to do it, as I really need to install this driver.

This is the only solution that worked for me.
cd /usr/local/include
ln -s ../opt/openssl/include/openssl .

You’ll need to install OpenSSL using homebrew, and tell homebrew to create necessary symlinks:
brew install openssl
brew link openssl --force
If you don’t already have homebrew installed, you can get it by running this:
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
And before all that, if you haven’t already installed XCode and the XCode command-line tools:
xcode-select --install

You can use environment variable C_INCLUDE_PATH to tell the compiler to include the path to openssl header files.
For example, if you just want to do it once:
sudo C_INCLUDE_PATH=/usr/local/opt/openssl/include pecl install mongo
