cURL has external library dependencies to support some of the protocols.
For https for example OpenSSL can be used; which is sometimes forgotten 
in custom cmake builds since it is disabled by default.

SFTP requires libssh2 which I assume isn't available/considered/enabled 
in the cmake release binaries.
