Subject: cmake: Export libcurl and curl targets to use by other cmake projects

The config files define curl and libcurl targets as imported targets
CURL::curl and CURL::libcurl. For backward compatibility with CMake-
provided find-module the CURL_INCLUDE_DIRS and CURL_LIBRARIES are
also set.

Closes #1879
