Unable to make/compile Plugin for Mongo

[ayushsharma82]

Hi Guys, First of all this is an Amazing Plugin and solves my authentication problems... I Tried making this plugin for mongo and also installed libmongoc-1.0-0 via package manager

apt-get install libmongoc-1.0-0

This is error which i get when i issue make command in mosquitto-auth-plug folder :

testuser@vultr:~/mqtt/mosquitto-auth-plug$ make
Selected backends:          MongoDB
Using mosquitto source dir: /home/testuser/mqtt/mosquitto
OpenSSL install dir:        /usr/bin

If you changed the backend selection, you might need to 'make clean' first

I have Tried installing Libmongoc by both ways, from package-manager and via git clone. The Issue remains the same. Please Help.

Solution: I was pretty dumb to not figure out fast. The Problem was that pkg-config was not installed in my Ubuntu Server.

Just install it by sudo apt-get install -y pkg-config

Plugin compiled successfully after this. Thanks again for this wonderful Repo.
