I had the same problem (openssl) and this worked for me on Ubuntu 14.04.1 LTS. The solution is the same up to Ubuntu 18.04 (tested).
sudo apt-get install libssl-dev

sudo apt-get install libssl-dev
fixed it on macOS using
brew install openssl
cmake -DOPENSSL_ROOT_DIR=/usr/local/opt/openssl -DOPENSSL_LIBRARIES=/usr/local/opt/openssl/lib
CMake cant find OpenSSL

CMake: Could NOT find OpenSSL
Windows build can't find OpenSSL
More recent OpenSSL versions (the 1.1.x series I think) slightly changed the formatting of how the version number was specified in the opensslv.h header. This caused CMake's version parsing code in its FindOpenSSL.cmake module to fail, which was then fixed around CMake 3.5.0. Furthermore, from OpenSSL 1.1.0, the library names on Windows are closer to their Unix counterparts and are named libcrypto and libssl (possibly with further suffixes) instead of the old names libeay32 and ssleay32. CMake 3.7.0 contained the update to account for this library name change. As a result of these two changes and fixes, if you want to use OpenSSL 1.1.0 or later with a CMake project, you should probably be using CMake 3.7.0 or later.
We had a similar problem with cmake 2.8.12.2 and OpenSSL 1.0.2u

To find out more details, you can add "--debug-output" option to cmake command.
In our case, it helped to specify the -D_OPENSSL_VERSION on cmake command line:
OPENSSL_VER=1.0.2u
cmake ...
-DOPENSSL_ROOT_DIR=$IDIR_BASE \
-DOPENSSL_INCLUDE_DIR=$IDIR_BASE/include \
-D_OPENSSL_VERSION="$OPENSSL_VER" \

I have it as can bee seen here
And it works
I'm not feeling well, I feel extremely tired, please help. I'm using Clion
(I'm new to build systems and adding libraries, if I have provided insufficient information let me know in the comments.)
I've installed openssl lib using brew to /usr/local/Cellar/openssl (macOS) and when I compile my project I get an error:
