When using static OpenSSL, HAVE_openssl test will fail, because of unresolved external symbols. These symbols are from Ws2_32.lib and Crypt32.lib, which CMake does not link by default. In qmake build system, we can use OPENSSL_LIBS variable to specify these system libraries. But there is no similar variable in CMake build system. Accordingly, we should let OpenSSL::Crypto target link these libraries.
