user10229: I am trying to build bitcoind on Ubuntu 16 64-bit. I have installed the dependencies and have built it fine many times on other machines.
During ./configure, I am getting
checking whether the Boost::Unit_Test_Framework library is available... yes
checking for dynamic linked boost test... yes
checking for mismatched boost c++11 scoped enums... ok
checking for SSL... no
configure: error: openssl  not found.

I have run sudo apt-get install libssl-dev and tried it, also tried brew install openssl, still no dice.
Before, I was getting a missing pkg-config at this point, even though I had installed it. I installed pkgconf and also installed it via brew, and now it's complaining about openssl, which is definitely installed.
$ which openssl
/usr/bin/openssl

Any ideas? Frankly, I'm stumped.
UPDATE:
I built openssl from source, now I'm getting this:
checking for mismatched boost c++11 scoped enums... ok
checking for SSL... yes
checking for CRYPTO... yes
checking for EVENT... no
configure: error: libevent not found.

I'm not sure what is going on... it seems it cannot find packages installed via apt-get for some reason.

user42875: I fixed the issue by installing extra libraries, the whole list
sudo apt-get install -y autoconf g++ make openssl libssl-dev libcurl4-openssl-dev

sudo apt-get install -y libcurl4-openssl-dev pkg-config

sudo apt-get install -y libsasl2-dev
