Starting with CMake 4.0, CMake doesn't initialize the CMAKE_OSX_SYSROOT variable with any value when running on a macOS host and no explicit CMAKE_OSX_SYSROOT or CMAKE_SYSTEM_NAME is set. CMake expects the platform compiler wrapper /usr/bin/c++ to pass an appropriate -isysroot flag to the underlying compiler, without CMake explicitly setting one. This mostly works, but the configure output will not show anymore the active sysroot path. Query the active path from xcrun, and display it in the configure output.
