openssl check does not work in cmake

[tobiasschweizer]

I forgot to install openssl-develon CentOS 7 but cmake did not complain. Then during the build, it failed (header files were missing).

Isn't cmake supposed to find out whether openssl-devel is missing?

I think that cmake only looks if the library is installed in the system, not if the headers are present.
