Extend the automatic export system of install(PACKAGE_INFO) and export(PACKAGE_INFO) to handle targets created with cmake_pkg_config, and allow find_package to resolve CPS requirements in the pkg-config domain. A pkg-config package has no components of its own, so it is exposed to CPS as a package named after itself with a single component of the same name; such references take the form "<PkgName>:<PkgName>" and resolve directly to the foreign target which provides the package. The domains in which a requirement may be found are recorded in a CMake extension section rather than a non-standard `domains` attribute.
