kou opened a new issue, #50005: URL: https://github.com/apache/arrow/issues/50005
### Describe the enhancement requested If we use `ExternalProject` and `CMAKE_FIND_USE_PACKAGE_REGISTRY` https://cmake.org/cmake/help/latest/variable/CMAKE_FIND_USE_PACKAGE_REGISTRY.html and running `cmake` twice like https://github.com/apache/arrow/issues/48801#issuecomment-4498889561, `RapidJSONConfig.cmake` in `${BUILD_DIR}/rapidjson_ep/src/rapidjson_ep-install/lib/cmake/RapidjSON/`. It's not intentional. If we use `FetchContent` instead of `ExternalProject`, it doesn't happen. ### Component(s) C++ -- This is an automated message from the Apache Git Service.
