CMake CI Cleanup

[cmazakas]

URL's find_package() CMake test doesn't actually invoke any methods defined in the found DLL for Windows platforms with BUILD_SHARED_LIBS.

This PR updates the test to use components of URL with out-of-line definitions which now triggers an expected CI failure.

The fix is somewhat straight-forward, just updating he $GITHUB_PATH in any step before the Find Package one in the ci.yml.
