Issue to fetch nlohmann_json

During cmake phase I got an error with CMakeLists.txt in tests/integration/harness folder.

FetchContent_Declare(nlohmann_json URL https://github.com/nlohmann/json/releases/download/v3.11.2/json.tar.xz DOWNLOAD_EXTRACT_TIMESTAMP ON) I got this error: -- Populating nlohmann_json CMake Error at /usr/share/cmake-3.22/Modules/ExternalProject.cmake:2806 (message): At least one entry of URL is a path (invalid in a list)

I notice Cmake somehow tried to download from https://github.com/nlohmann/json/releases/download/v3.11.2/json.tar.xz DOWNLOAD_EXTRACT_TIMESTAMP ON instead of correct URL. I tested this with CMake3.18.4 and Cmake 3.22.1.
