I've attached a new patch without the changes to the singular-named variables.

Subject: [PATCH] FindOpenSSL: Link libraries needed for static OpenSSL.
OpenSSL depends on system libraries. When linking statically again
OpenSSL, the client target must also link those libraries.
This patch updates FindOpenSSL.cmake to include the necessary system
libs in the OpenSSL libraries variables and in the OpenSSL::Crypto and
OpenSSL::SSL target properties.
The dependencies:
Windows: crypt32
Unix: CMAKE_DL_LIBS
