When detecting these dependencies via CMake Config and their main imported target is undefined, automatically assume and use their static imported target instead. Adopting from vcpkg downstream, where it's done for nghttp3 and ngtcp2, but not for nghttp2. Refs:773e092a82/ports/curl/dependencies.patch70b941a5d2Downstream-patch-by: Kai Pastor Closes #21470
