Please don't top-post [1] it makes the conversation hard to follow.
Either libcurl or one of its dependents is dependent on bcrypt. Official
builds don't need bcrypt. You can use Dependency Walker [2] to see
exactly what DLL needs bcrypt. As I said it's possible you are building
curl in a way that requires bcrypt but I don't know what that is. It
would help to know exactly how you are building curl.
