Soon to be updated obs-deps built on CI will retain CMake package files created while building dependencies. When CMake uses packages, the usual triplet of variables from finders are not set. `CopyMSVCBins` relies on one such variable. This PR sets the `CURL_INCLUDE_DIR` if the cURL target is present, but apparently imported as a CMake package, to ensure prior functionality is restored.
