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

# (From Daniel Stenberg) The cmake build selected to run gcc with -fPIC on my box while the plain configure script did not.
# (From Daniel Stenberg) The gcc command line use neither -g nor any -O options. As a developer, I also treasure our configure scripts's --enable-debug option that sets a long range of "picky" compiler options.
