I removed the paragraph of the question and added the following one:

 | The patch changes OPENSSL_LIBRARIES variable to fix the issue with
 | static linking of OpenSSL libraries. It also changes CURL_LIBRARIES in
 | the same way, however this does not alter any visible behaviour, because
 | OPENSSL_LIBRARIES is added to CURL_LIBRARIES. The latter change was made
 | to unify the way to choose libraries to link with: it is pure
 | refactoring part.

Hope it clarifies why I touched FindCURL.cmake.

Rebased the branch on top of the current master.

branch: Totktonada/gh-4437-fix-static-openssl-build-full-ci

WBR, Alexander Turenko.
