FindOpenSSL's OPENSSL_USE_STATIC_LIBS has no effect on windows

When using the OPENSSL_USE_STATIC_LIBS flag on downstream project, I am able to link statically with OpenSSL on Linux and OSX without any issue.

However, on windows, the flag does not appear to have the expected effect. The outcome of find_package(OpenSSL REQUIRED) provides the path to the import library libcrypto.lib instead of libcrypto_static.lib.

Found OpenSSL: path/to/libcrypto.lib

How can we force the use of libcrypto_static.lib?
