  "message": "Experimental/CXXModules: Implement EcoStd Module Metadata parser\n\nAdds a parser and serializer for the EcoStd Module Metadata format\n\nRFC: https://github.com/ecostd/rfcs/pull/3\n\nThis adapts the existing experimental support for import std; to use\nthe new parser. The CMAKE_CXX_STDLIB_MODULES_JSON is now the canonical\nvariable for controlling how CMake discovers the stdlib module metadata,\nand is used directly by compiler detection.\n\nToolchains can still override the __CMAKE::CXX## targets if they wish,\neither in conjunction with CMAKE_CXX_STDLIB_MODULE_JSON or not. It is\npossible to disable automatic detection of\nCMAKE_CXX_STDLIB_MODULE_JSON by setting it to the empty string.\n\nWhen available, the CMAKE_CXX_STDLIB_MODULE_JSON will be used to create\nall requested C++ stdlibs which do not already have targets.\n",
