Using OpenSSL crypto library without SSL library no longer possible
OpenSSL is split in two parts: The SSL and the crypto library.
If you only needed the crypto library, it was enough to provide the crypto library, call find_package(OpenSSL)
and then check whether target OpenSSL::Crypto
exists.
However, starting with commit 696339a9 you always have to provide both the SSL and the crypto library, otherwise none of the targets will be created.
